Have now been able to read through the 294 Sqn ORB which includes the Sharjah detachment. The first aircraft from 294 arrived at Sharjah on 17 July 1945 and the detachment was declared operational two days later. It had examples of all three types of aircraft (Walrus, Warwick and Wellington) that 294 operated on it. The detachment was withdrawn on the squadron's disbandment in April 1946.
The only loss recorded is to Wellington HZ976/G which I mentioned above. The only other loss near that area recorded in the ORB involved a USAAF C46 en-route Jask to Abadan. This aircraft was reported missing on 27 July 1945. Wreckage was sighted by a DC3 on 29 July 1945 and a Walrus aircraft from 294 was sent to the area to guide a road convoy to the site.
The ORB records the location of that wreckage as a bearing/range from Sharjah. It is given as 160 Sharjah, 20 nm. The serial number of the C46 is shown as 7353. No other details are recorded other than there were no survivors.
I think that location is well away from the position of the wreckage seen by SARO.
