Just a random though: has anyone checked how long, and over what distance, the plane could fly from its cruise altitude once its engines stop ? If, in such a situation, the pilots tried something similar to what has been done with flight 1549 (https://en.wikipedia.org/wiki/US_Airways_Flight_1549), it might be an interesting approach to try to approximate a circular search zone (rather than an area).
From the article:
"To ensure that the Administration does its best to protect these innovations and creative products, today the President issued this Executive Order, which establishes a Cabinet level Senior Intellectual Property Enforcement Advisory Committee comprised of the heads of the Departments responsible for intellectual property enforcement, including the Departments of Justice, Homeland Security, Commerce, Health and Human Services, State, Treasury, Agriculture and USTR. The Executive Order also establishes the Intellectual Property Enforcement Advisory Committee comprised of representatives from the agencies responsible for designing and carrying out the Administration’s strategy for stopping intellectual property theft."
Gotta love that doublespeak."

So far, LTTng has been mainly integrated in embedded distros: WindRiver Linux, Montavista Linux and STLinux currently ship with LTTng. The interesting news that is particular about Ubuntu here is that, by installing the LTTng packages from PPA, it is now possible to easily deploy the LTTng kernel and userspace tracers on a desktop-oriented distribution.
The K42 project at IBM Research investigated the benefit of a complete OS rewrite with scalability to very large SMP systems in mind. This is an open source operating system supporting Linux-compatible API and ABI.
Their target systems, "next generation SMP systems", back in 2003 seems to have become the current generation of SMP/multi-core systems in the meantime.
