I can't remember seeing any Gulf Aviation DC 3's at Sharjah during 1959-61, only Doves and Herons, but they must have been used regularly as a wet leased Kalinga Airlines DC 3 crashed in 1960. I don't know if it had been in G A colours
On 10 July 1960, the thirteen passengers and three crew on board a Gulf Aviation Douglas C-47 (registered VT-DGS) died when the aircraft crashed during a flight from Doha to Sharjah. As the wreckage could not be located, the cause for this worst accident in the history of the airline could not be determined.[10]
The wreckage was in fact found several years later, about 30 miles east of SHJ.
