Recently, the earth flew through the tail of the comet Tempel - Tuttle. To Earthlings this is manifested as a meteor shower. And during the expected peak meteor shower, we launched a ball. Before me was to check welded black box, which stores the various parameters of interest to us - the height, location, temperature on board and overboard, and others. But in parallel, at the suggestion of Albert , decided to try to catch a shooting star in the frame. To do so, had to take a chance with two DSLRs ... And one of the thousands of frames, there is something very much like a meteor. I do not know whether kakih-nibud amateur astronomers in the world still picture of a meteor flying past the lens in the stratosphere and in this we do not compare with anything ... but it seems that we now have. :)
See "scratch" on the left? ...
This is a fragment of a comet had entered the earth's atmosphere at a speed of 70 kilometers per second, and burned in front of the lens of our probe at an altitude of 13km.
It is surprising that this happened at dawn, when the exposure was reduced as much as to 1/2500 second. (Usually on the ground to catch the meteors long excerpts from a few seconds to several minutes)
But the test results on-board electronics:
Because of the strong overload (two SLRs weigh too much), the ball rose slowly and stood up only to 14 km (upper graph). (X-axis was slightly less than three hours). But at a temperature lower than behind - 50 within our unit, it has always remained above zero (lower panel).
And here is how the trajectory.
Once again, thanks to developers GPS beacon Auto-Von for the fact that their device has determined the position and was able to send them where our phones are subsequently refused to catch the network.
In addition several Natasha's gallery launch and retrieval process. Well, a couple of shots of the flight.

Figase! 0_o Krutoten!
What kind of lens, and you pressed the shutter!
The height and range?
