So Chopjock, the pilot flies your ‘corner’ departure, just clears the stadium roof then 30seconds in at 60kts and 300ft still at high power has a tail rotor failure, he’ll be performing some form of emergency night autorotation onto dark roads and houses vs some form of vertical descent potentially into the lit stadium. Not a lot in it, both horrendous situations.
However had an engine failed instead which statistically is 1000 times more likely according to JimL’s certification stats, he would have a) (corner departure) collided with the stadium, or b) (Cat A) landed back onto the take-off spot without incident.
