They didn't eject. They say they lost the chopper last evening. Last evening we had a bloody blizzard with heavy fog over here, I wonder if the spell reached them.

Gr.Viper 131 Posted March 13, 2012 The design of the rotors always made me wonder as an Aircraft wing flexes in flight and under load do the rotors do the same ? Yes, the edges go up. More so on the side where the blades are running into the air flow. So on Ka two rotors going in opposite directions do come closer in flight on one side. Single rotor isn't without trouble either - careless handling of Hind can chop its tail off, and stuff like retreating blade stall and vortex ring is generally dangerous.

Gr.Viper 131 Posted March 15, 2012 Preliminary results of the investigation are in and point to the crew losing orientation at night in a snow storm. Probably didn't eject for the same reason. *sigh* Share this post Link to post Share on other sites
