My grandfather was a flight lieutenant in a glider squadron (669) that spent most of its time training near the end of WWII and almost all of his flight logs were in the de Havilland Tiger Moth for the time he was there. I assume they may have been the rig that towed the gliders, but I can't find a reference saying as much. I'd love to know more.
Thanks in advance.
The Tiger Moth was one of the principal training aircraft of the time for the British + Commonwealth air forces, so it makes sense that new glider pilots would be initially trained on the type. However, I would doubt that they would be involved in towing anything- the DH.82 was a very light aircraft and probably wouldn't have enough power to pull much off the ground. American C-47's and British Avro Manchester's were the principal RAF glider tugs during the war.
