The third variant of the Hotspur was the GAL.48B "Twin Hotspur", which did not progress past the prototype phase. The Twin Hotspur was a 1942 attempt to create a glider capable of carrying 15 airborne troops as an interim glider until production of the Horsa reached sufficient levels. It was created by connecting two Hotspur fuselages together, using a constant-chord centre wing section of length, and a constant-chord tailplane. Two pilots sat tandem-style in the port fuselage. In August 1942, the sole "Twin Hotspur" prototype (MP486) underwent testing, towed behind an Armstrong Whitworth Whitley tug. The project was abandoned before production could begin, primarily because the glider's flight characteristics were criticised by its pilots.
