A helicopter crash occurred during a lesson. The incident happened when the instructor made an adjustment, causing loss of control. This action led to the helicopter moving backward and descending before hitting the ground. It then became airborne again, only to crash a second time.

The National Transportation Safety Board investigated the incident and released video footage. Fortunately, the instructor and student were not seriously hurt.

Further details about the crash, including the type of helicopter involved, are available from the National Transportation Safety Board's investigation.
