Radio control airplane up to a height of 2177 meters.

Blue Panther basement measuring approximately 1 m between the wing tips. With 100 watt motor and accumulator of capacity in 2100 milliampere hours, the plane weighs 450g. Then there is also control electronics, gps and pressure gauges on board.
The plane was built by students at Stanford University and the test flight took place on the testing ground Nasa Dryden Flight Research Center in the Mojave Desert. It is not radio controlled, but must clear navigation on their own.
When the plane flies at such high altitudes is a risk of collision with the real airplanes. Would it come off course and lose contact with ground control, it will automatically make an emergency landing.
That was what happened when the students after the 2177 meter record of 11 September in the visibility of reaching 2500 meters. Gusts of wind took the plane off course so that it risked ending up in airspace reserved for the U.S. Air Force.
Emergency landing technique worked, but on landing the plane was damaged and the measured flying height of 2490 meters were not accepted as a record.
