Hey AC
Highest in a JetBanger was 17,440' but it was 16C so was t4'd out & could not pick the Patient, so the Sherpa Guides carried him down to a lower pinnacle at 16,400' whilst I waited at base-camp. From where I could dive off to escape with him
Not the composite tail-rotor blades hmmmm that would be good, there good on the 47
Land Happy always
