I would rate Tekin a few degrees more challenging than Oksapmin... I wonder what time of day it happened? The place was a mandatory check-in airstrip and taboo in the afternoons, once upon a time, due to the wind issues. I have sat at the top of the strip watching the windsock to time the takeoff there once when it was getting lively. Still ended up with full aileron control deflection and some rudder to pick up a dropping wing soon after getting airborne... The rotor turbulence there can be nasty... Pleased to hear that the tuff truck must have protected the occupants sufficiently on this occasion with no injuries reported!
