Hi Andrew, Jefford's book RAF Squadrons shows the following Sqn numbers served at Chaklaka in the time frame you mentioned.
10 SQn Dakotas
298 " Halifax A7
670 & 672 Gliders
So it's possible he was something to do with planned operations involving Daks etc towing gliders for use against the Japanese.
Other squadrons did time there but not on those dates.
