Hi Ed
nice weather ,....nice views..... but the pilot was not able to
maintain position,... I would not recommend that pilot for any
rescue operation...;-)
He should have been steady above of any of these "landmarks" maybe
easier said as done......
Good luck for next try.
I prefer a crane, the position is quite steady.... http://
