Disastrous landing : the Robinson R44 Astro helicopter crashed on a car

This Robinson R44 Astro helicopter crashed on a car in Kroonstad, South Africa. One pilot and three passengers were on board. There were no fatalities and only minor injuries were reported.
Investigation determined that the pilot had inadvertently switched off the main hydraulics instead to switch the speaker to the on position. The pilot therefore had no control of the aircraft prior to impact.
