It was just publish that Russian Military subcontractor Ruskie Dioprie
developed the new type of optical lens. For a military application
of supersonic flighta on very low altitudes it suppose to detect any
turbulence in the lower leyers of atmosfhere. It should detect the any
vertical movement of air with an accuracy of 1/20 meters per second,
and in the radius of 25 kilometers. The small size of lens and the
low energy consumption maks it an ideal instrument for glider pilots.
More information tomorrow, on second day of April.


Yes, but I understand that it is so heavy that you need a 100 meter
wingspan to support the weight. When the device was tried at a gliding
club in Russia, they had to build a new extra-wide runway.
