While performing a public aerobatic show 2 FMA AT-63 jet trainers colided in middle air. Both aircraft quickly declared emergency but eventually managed to land safely despite some electrical and hydraulic failures. The structural damage in flaps and wingtips could be seen in the photographic secuence. This type of aircraft is the same of the crazy low pass already featured in LL. http://www.liveleak.com/view?i=68f_1306880662&;
