I remember being weathered in at Hayfield in Derbyshire with a Bell 47. We had a visit from the local police to tell us that the local children were using it as a climbing frame. Apparently the young ladies involved were enjoying swinging through the tail rotor guard!!!!
Going in to work one morning at Sywell we found a Bell 206 parked outside with the doors swinging in the wind and with the battery left on and flat.
Apparently the late night motel goers had been having a bit of fun.
Hangarage was available, but the operator was too mean to pay for it. Cost them a lost days revenue plus the cost of sending an engineer and battery.
Leaving any aircraft parked out is a risk even on an airfield.
