Russains are sometimes a bit crazy, like kids =)
Remember that once during the regular parachute-jumping trainings there was capt. Schukin, PIC of the Mi-8 chopper (which we use to climb the altitude 800-4000 meters and to jump out from), one of the best amusement for him was to fly on his helicopter over the "Start Point" (place where we pack our parachutes) at the five or seven meters. An average time to pack the d1-5u parachute is 20 or 30 minutes, and after his "ace's flight" over our heads we had have to pic up our almost packed parachutes, disentangle them and pack them again. By the way, each skydiver, repacking his parachute, did thumbs up for Schukin, mad enough to fly so low despite two or three colonels on the Start Point and some commanding officers on the tower =)
