Rumour has it that a Careflight Kingair allowed a stretcher to come into contact with a turning propellor. (hope there wasn't a patient on it)
They apparently flew down another Kingair, ripped the prop of that one, placed it on the stricken aircraft and flew it back to Darwin leaving the donor Kingair there.
Not sure of the prop strike protocol on a PT6, piston would require bulk strip, now where is that PW manual....
