No cleaning bill but the very afraid passenger in the front seat was a bit of a distraction! The only injury was a bloody nose when he accidentally grabbed the collective in his thrashing around. There was a guy in a 500 about 1/4 mile behind me who saw the event and landed just in front of me as the rotors were slowing down ( I kept the pax in the aircraft until they stopped ) His comment on the radio : "WOW was that ever neat!" He told me later that he was very impressed with the explosion of the engine. LOL
