One of the rarest aircraft to pass through Sharjah as there were only 7 built. I saw 5 but was only able to photograph 2 as they mostly tended to land after dark and leave at daybreak. Build date:- 5th June 1964. On delivery to India, became VT-DVD with the "Aviation Research Centre" which was created by the Indian Intelligence Bureau in cooperation with the CIA. The H500's were used to infiltrate agents into Tibet(amongst other duties!) According to the pilot this was the last one for delivery.
