April 26th, 1987 - Rubidoux, CA, USA - This Hughes 269b went out of control and collided with the ground during a take off to a hover. The pilot was learning to fly it. He was scheduled for his
first flight lesson on the day of the accident. The instructor told the student pilot to wait for him and not to touch anything. While waiting for the
flight instructor, the student pilot started the aircraft, ran it up to full rpm, and then began to increase the collective pitch control. The helicopter
climbed vertically to a high hover and the pilot lost control. He received minor injuries.
