Submission + - Air Force believes anti-g suit is cause of F-22's oxygen problems (flightglobal.com) 2

wired_parrot writes: The USAF believes it may have identified the root cause of the F-22 Raptor's oxygen troubles: pilots are running into physiological limitations in attempting to breath oxygen while under high-g loads, leading to a condition know as acceleration atelectasis. This is being aggravated by the anti-g suit worn by pilots, which puts pressure in their chest. It may be that the F-22 has reached the edge of what a human pilot can handle

The European Grand Challenge 61

An anonymous reader writes "A European version of the DARPA Grand Challenge is being held in Germany next month. Instead of a race through the desert, the EU challenge is split into three events. Urban, non-urban, and landmine detection will be the 'courses', with multiple winners in each event. Interestingly Sebastian Thrun, winner of last year's Challenge, has been forbidden from taking part despite being a European citizen." From the article: "The trials will take place in and around Hammelburg, a mockup of a town used by the German military for training exercises. In the non-urban course the robots will have to contend with a one-kilometer route containing ditches, barbed wire fences, cattle guards, fires, narrow underpasses, and inclines of up to 40 degrees. The urban and landmine 500-meter trials will require the robots to negotiate doorways, stairs, partially collapsed buildings, and poor visibility from smoke or partial lighting. Along the way, they will also have to search for designated objects and report their findings back to base."
