Analysis

A helicopter laying on its side was found by the manager of the Houghton lake state airport when he opened for business. The owner of the helicopter reported the helicopter was stolen during the night. Several weeks later the police arrested a female who admitted she stole the helicopter to help her boyfriend escape from prison. She had a student helicopter certificate and about 10 hours instruction. She said the helicopter crashed and rolled over while she was trying to land in high winds.
