In answer to this question, I believe the Dutch destroyed most of the Ju-52's when Germany invaded Holland. Notice that German airborne assaults did not occur in the France campaign or in the Russia campaign, primarily due to a lack or shortage of transports.
Er... No. The GErmans lost around 400 JU-52s in Holland and Norway. Why werent they used in France? Er... Look at the dates for the landings in Holland and Belgium! The airborne strikes breached the canal and Eben Emael pushing forward the Northern German spearhead. Their use was in direct support of the attacks on France. It further gave the impression that Germany would attack France via the Low Countries. As for Russia... Perhaps you forgot Operation Mercury? The capture of Crete? If as you say no airborne attacks were launched due to a lack of transport then what about Crete in May 1941!!! German airborne operations put immense strain on the Transport Fleets. The German need to secure an airfield by drops and the use of airlanded troops meant that many Ju-52s were damaged when airfields could not be secured and they had to land at any available place. Heavy losses were sustained to the transport fleets in all German operations but the more serious losses occured in trained pilots for the training establishments. The reason for no airborne assaults in Russia are due mainly to the heavy losses of the Fallschirmjager on Crete rather than any losses in aircraft, though it has to stated that their need is debatable in Barbarossa. Brandenburg units seemed to have secured most key bridges with just as much success. I dont believe that Barbarossa really require the FJ use hence the willingness of Hitler to allow their use in an operation that was expected to sustain heavy losses from the outset.
OK, the channel ablaze was one of wartime propaganda rumours a.k.a. sibs. http://www.psywarrior.com/DeceptionH.html The topic 2nd from top.
