Subject: Rocket plunges into Indian Ocean
On 21 Sep 2001, a Taurus rocket went off-course 83 seconds after launch.
Carrying an Orbital Imaging satellite, a NASA ozone-monitoring QuikTOMS
satellite, and the cremated remains of 50 people ($5300 each), the rocket
failed to reach its intended altitude and velocity despite an attempted
correction, resulting in loss of the payloads. NASA's share of the cost was
estimated at $50M. It was the second Orbital Sciences rocket lost in less
than four months. [Source: AP item in Newsday.com, 22 Sep 2001, PGN-ed]

Nature, the journal that told us about cold fusion, posts summaries of
recent physics papers at <http://www.nature.com/physics/>. One of
these, "Bose, Einstein and chips," reads:
On the atom chip, the magnetic potential minimum that confines
the atoms is barely a millimetre or so wide, and it holds the
condensate an ultracold cloud of around 1,600 rubidium atoms
about 70-440 mm above the chip surface.
Or, as a read-source-ful scientist might discover:
about 70–440 <span class="symbol">m</span>m above the chip surface.
The online version of the article they are summarising [W. Hansel et al.,
Nature 413 p498 (2001)], gives the correct height of 70-440 micrometres.
The micro symbol is included in ISO 8859-1.
Unlike the ohm/watt confusion reported earlier (Rolph, RISKS-21.29 and
Peuhkuri, RISKS-21.33), millimetres and micrometres have the same

Subject: AOPA's TurboMedical(sm) eases medical application process
AOPA's TurboMedicalsm eases medical application process, 24 Aug 2001
AOPA has launched a new, Web-based tool to help pilots prepare to obtain
their medical certificates. AOPA's TurboMedicalsm is the first of a series
of "intelligent" online forms to come from AOPA. Pilots who use
TurboMedicalsm will be less likely to have FAA delay or deny the issuance of
their medical certificate.
"AOPA's Web site (www.aopa.org) offers more resources to pilots than any
other aviation site on the Internet," said AOPA President Phil Boyer.
"TurboMedicalsm is an innovative way to use the Web to remove some of the
uncertainty of applying for a medical."
The innovative online form "interviews" the pilot to ensure that all of the
information on FAA's Form 8500-8 (application for an airman medical
certificate or student pilot certificate) is filled in correctly.
TurboMedicalsm checks the pilot's answers, and flags anything that might
cause problems in issuing a medical certificate.
"FAA's Aeromedical Certification Division is currently taking up to three
months to review medical applications," said Gary Crump, AOPA director of
medical certification. "Some 30 percent of those delays are caused by
simple errors on the application form."
TurboMedicalsm checks for those errors.
The online form takes pilots step-by-step through the 20 question areas on
the medical application form. For each question, the form explains exactly
what FAA is looking for and why it is asking the question. And there are
links to AOPA's expansive online medical data for more information.
The form provides advice on the best way to answer each question. For
example, TurboMedicalsm tells a pilot that it is usually best to apply for
the lowest class of medical that you actually need. Under FAA regulations,
even CFIs need just a Third-Class medical certificate to provide flight
instruction for compensation, although employers may require a higher class
TurboMedicalsm is particularly useful in helping the pilot answer the
medication, medical history and medical visit questions.
When a pilot answers the question, "Do you currently use any medications?"
TurboMedicalsm checks the answer against AOPA's list of FAA-accepted drugs.
For example, TurboMedicalsm will tell a pilot that the popular
over-the-counter drug Benadryl is acceptable to FAA as long as the pilot
waits 24 hours after taking it before flying.
But if the drug isn't on the list, TurboMedicalsm will flag it and provide
links to more information. There is even a direct email link to AOPA's
medical experts so the pilot can ask specific questions.
If a pilot answers "yes" to one of the medical history questions,
TurboMedicalsm will search for key words in the explanation to be able to
provide more information to the pilot.
A pilot can skip a question and return to it later. TurboMedicalsm will
temporarily store the answers. A pilot can choose how long TurboMedicalsm
will store the answers.
Once a pilot has completed all of the questions, TurboMedicalsm will review
the form for completeness and accuracy. The pilot can then print out a copy
to take to the medical examiners office. Pilots should also keep a copy in
their personal records.
"TurboMedicalsm is an educational, self-help tool to help pilots prepare to
complete the medical form in the doctor's office," said Crump. "But for the
future, we're working on an 'FAA-approved' version of TurboMedicalsm that
you can complete online and email to your FAA designated medical examiner
prior to the examination."
The 375,000-member Aircraft Owners and Pilots Association is the world's
largest civil aviation organization. More than one-half of the nation's
pilots are AOPA members.
1. I am no expert, but I question the assertion "All of a pilot's answers
on the TurboMedical(sm) form remain absolutely confidential. No one but the
pilot will ever have access to the medical information. Data is stored on a
secured server and data transmissions are encrypted." We have been told
*many times* in other contexts that certain medical data is confidential,
but absent a doctor-patient relationship, I think this is generally a very
tenuous assertion. I am pretty sure there is no doctor-patient relationship
created with this form.
2. "[D]ata *transmissions* are encrypted...." (emphasis added) is not
synonymous with "the data is encrypted." If the data is stored on a secure
server without encryption, it is still readable by anyone with access to
the machine. If the data is encrypted where it is stored, only the person
(with well-publicized exceptions) with the "keys" can access it. There is a
world of difference.
3. The data is stored on a secure server, but I really don't know what that
means. I think my IRS data is on a "secured server," but how many stories
do we see where that data has leaked out? Medical data is *far* more
sensitive to release than financial data, and I am less concerned with
interception in transit than I am with security breaches from the server
where the data is.
4. If data is stored "on a secured server" for a specific period of time,
what becomes of the routine backups made? Are they periodically destroyed?
If not, this information is probably obtainable indefinitely.
5. Are the links to the medications database stored? If I check on a
medication, is the fact I did so recorded? It probably is on my client, and
I wonder what "cookies" are employed.
6. I have not used the system (nor am I likely to), but I wonder what
"disclaimers" are associated with using it. This kind of information might
fall under the Fair Credit Reporting Act (which can have a very broad
reach), and a user might have to authorize far more than what is advertised.
The RISKS of this system far outweigh its usefulness. We need a machine to
tell us how to fill out a form? If you have medical issues, you discuss
them with your *doctor*, and he fills out a form. For a fee, of course, but
I for one, am willing to pay a reasonable fee for privacy.

Subject: Ham radios in the aftermath of 11 September 2001
As others have noted, the terrorist attacks of 11th September caused major
disruption to land-line and cellular phone communications. What hasn't been
widely reported is that 570 Amateur (ham) Radio operators from 35 states and
two Canadian provinces provided auxiliary radio communications to relief
agencies operating in the affected areas.
The lesson is that even the most modern communications technology can fail,
and that there is still value in having an independent communications

Subject: 11 Sep 2001: Risks of electronic surveillance
In the aftermath of the September 11 terrorist attacks on the USA, a special
feature on automatic electronic surveillance (i.e. Echelon, Carnivore, spy
satellites, and all that) was broadcast by the BBC ClickOnline, hosted by
Stephen Cole, Sep. 22).
The feature included a lengthy interview with Dr. Kevin O'Brian of RAND
Europe about the failure of US intelligence to gather enough information to
pre-empt the attacks. Of particular interest to RISKS readers is the
following quote from Dr. O'Brian:
"We've seen reports that they may have actually been spoofing or
misdirecting intelligence services quite knowingly, and that they
are aware of the fact that they could use the technology against
the intelligence services by sending out false signals by sending
out false reports and rumours, by using technology such as mobile
phone communications or Internet messages to actually misdirect
the intelligence services' gaze away from their attacks."
The risks are obvious: The over-reliance on massive computer-based automatic
systems for scanning and filtering that has characterised much of US
intelligence gathering in the post-soviet era can only be effective as long
as the bad guys are not aware of what you are doing. The simple fact that
computers systems are rule-based (and AI-systems exceedingly so) permit
enemy agents to play clever counter-intelligence games, where plotting the
response to certain stimuli can be used to "map out" in detail how an
automatic surveillance system will respond to diverse inputs and hence
"learn" how to misdirect the system on a massive scale.
A human-based intelligence system, in particularly a highly organized one,
is of course also vulnerable to this type of attack, but the rule-based
nature of an AI-based system makes the attack easier and more reliable

I first learned of the event by connecting to a local news site here, at
about 4 p.m. local time (which was 9 a.m. EDT). At first try, the site was
down; when I finally got in and looked at the headline "Two Airliners crash
on NY's WTC" my first reaction (probably the result of reading too many
RISKS issues) was "they let their test page leak out as if it were real
It seems that this "this isn't happening" initial reaction was shared by
many, even some to whom this was actually happening. This had never
happened before, and even though technically possible, the perceived risk of
its realization was considered unreal.
The main risk is, IMHO, of evaluating the relative costs and benefits of
preparing for an eventuality which, by our common sense, is very improbable;
while the perpetrators seem to be making their evaluations by a completely
different set of priorities and morals. How do we apply "crazy logic" to
risk assessment? When do we apply it, and how crazy can we get before
making the very notion of assessment senseless?

Subject: Remote control of airliners
The Associated Press reported on a test of a remotely-piloted 727. The
utility of such a scheme is clear, in the wake of the recent attacks;
to the reporter's credit, the article spent most of its space
discussing whether or not this would actually be an improvement. The
major focus of the doubters was on security:
But other experts suggested privately that they would be
more concerned about terrorists' ability to gain control
of planes from the ground than to hijack them in the air.
I'm sure RISKS readers can think of many other concerns, including the
accuracy of the GPS system the tested scheme used for navigation (the
vulnerabilities of GPS were discussed recently in RISKS), and the
reliability of the computer programs that would manage such remote control.

Preventable Deaths and Injuries during Magnetic Resonance Imaging
To the Editor: In July, a six-year-old child undergoing magnetic resonance
imaging (MRI) in New York suffered a skull fracture and intracranial
hemorrhage after an oxygen tank that had been brought into the room was
pulled into the machine at high speed. He died two days later .
Undetected or misplaced metal objects have caused numerous injuries during
MRI. Twenty-four of 46 MRI facilities responding to a survey in 1999 (52
percent) reported the occurrence of MRI-related accidents . Large
objects involved in such incidents included an intravenous-drug pole, a
toolbox, a sandbag containing metal filings, a vacuum cleaner, mop buckets,
a defibrillator, and a wheelchair, among others. Five incidents involving
oxygen or nitrous oxide tanks, one of which caused facial fractures, have
recently been reported .
To prevent such incidents, most imaging facilities currently provide safety
training to employees and administer patients a standardized questionnaire
about implants and other embedded foreign bodies before an MRI examination
is performed. Although these efforts prevent many injuries, they are
inherently limited. System-wide strategies to decrease the incidence of
serious errors are important.4 Safety interventions that work continuously
and automatically are generally far more effective than efforts to train
large numbers of employees or to enlist the assistance of large numbers of
The use of metal detectors over the doors of MRI examination rooms could
have prevented every one of the large metal objects listed above from being
brought into the MRI rooms and would have prevented the recent death in New
York. Highly sensitive walk-through metal detectors, such as those used in
airports, are available commercially for about $2,000 to $5,500 and require
minimal maintenance. By comparison, a typical MRI unit costs approximately
$1.3 million annually to operate and generates net revenues of $1.8 million
during use in more than 3000 patients, resulting in an annual net profit of
approximately $500,000 . The cost of installing a metal detector could
thus easily be paid for with operating revenues. Factoring in liability
savings would further decrease real costs.
Metal detectors should not replace the screening protocols currently in use,
since the detectors may be insufficiently sensitive to detect small
implanted metal objects, such as aneurysm clips or cardiac pacemakers. Their
installation would, however, be an inexpensive, simple, and potentially
life-saving addition to current practice.

Subject: Trusted Computing, and Embedded and Hybrid Systems - new NSF programs
The Computer-Communications Research Division (C-CR) of the Computer and

Science Foundation (NSF) is pleased to announce two new programs whose goal
is reducing the number of submissions to this valuable newsgroup,
comp.risks. For each, the due date is 5 Dec 2001, and $4M-$6M may be
available to support 20-25 awards, subject to the usual caveats.
** Trusted Computing (TC), NSF 01-160,
TC seeks to establish a sound scientific foundation and technological basis
for managing privacy and security in a world linked through computing and
communication technology. This research is necessary to build the secure and
reliable systems required for today's and tomorrow's highly interconnected,
information technology enabled society. The program funds innovative
research in all aspects of secure, reliable information systems, including
methods for assessing the trustworthiness of systems.
** Embedded and Hybrid Systems (EHS), NSF-01-161,
Past research in embedded systems has focused primarily on
resource-impoverished computational environments: algorithms and software
that must execute on memory-, processing-, and power-constrained
processors. The computational design was simple and synchronous to maximize
effective operating rates, and a great deal of design effort went into
optimizing performance under these conditions. As processing speed and data
capacity have increased and demands for automation have expanded, the nature
of the problem has changed. Now, hard and soft real-time processes must
interact, and they may be required to share the same resources. Applications
such as distributed control demand communication, which introduces
variability in operation. A scientific foundation currently is lacking for
systematic development and integration of physical and computational
components in embedded systems. This lack is particularly severe for
increasingly complex, distributed embedded systems. Empirical reports show
that relying on brute-force testing for verification and validation of
software for modern embedded systems can push certification costs to at
least half the total cost of the software. Scientific principles and
supporting technology are needed to assure that requirements are met during
development of software-based systems, in order to reduce the cost of
evaluating dependability and certifying that a system is fit for
operation. NSF investment is critical to sustain, adapt, and expand the
National research and development capacity in embedded systems.
