"the failures and near-failures"
Any operation is subordinate too, and integrated with, a larger scheme at some degree of perspective. Unfortunately, almost by definition, Airborne ops (especially WW2) seem to be totally unrealistic in execution due to unrealistic expectations and the over-confidence of the commanders involved. Resulting in "iffy" contingencies to bail them out being not so iffy after all. You had "crack" outfits filled with some of the best soldiers, and the most "gung ho" commanders, all of whom were watching the war pass them by. With higher going "why do we have these uppity prima donnas sitting around eating their heads off when I could be using them as shock troops in a leg infantry role".
When were gliders used to transport heavy equipment"
Normandy...I'd have to look, but the 82nd alone had 3 battalions of organic arty. Lotsa pics of jeeps, pack howitzers, and AT guns. Each line battalion, IIRC, had an organic mortar section with tubes, jeeps, and trailors. Lotsa gliders, lotsa big heavy stuff...
Market Garden..."Gliders also brought in 1,689 vehicles, 290 howitzers and 1,259 tons of ammunition and other supplies"
Arnhem; Pic being worth a thousand words...Polish AT gun brought in by glider. Looks like a 6 pdr./57mm
