Exercise with 2nd (blue) and 3rd (yellow) division (two four ship formations). Poor weather conditions with clouds postpones the exercise. Martin Blue (2nd) division takes off when conditions improves but when Martin Yellow (3rd) division takes off the visibility are poor with clouds. Yellow leader wants to climb and break clouds, approved and in line with briefing. However the fourship collides with the frozen lake Glottern ,slight right banking and diving 10-30 degrees.
Investigation comes up with two probable causes:
A: pilot error, group leader took off with main instrument "kurshorisont" (horizon, angle, compass) in locked position. Tried to seek ground reference but collided with terrain (probable).
B: instrument failure, main instrument (less probable).
Pilot Bengt H Nilsson killed.
