During World War II, the Nazi Luftwaffe also used giant six-engine Messerschmitt Me 323 Gigant transport planes. These truly gigantic machines could hold up to 12 tons of payload, including such sets as crawler tractors with cannons or trucks with trailers. However, their disadvantage was a relatively large vulnerability to enemy fighter planes. The designers tried to counter this by consistently armoring the crew's section, especially the cockpit.
A fragment of armored glass, probably from the front plate of the Messerschmitt cabin, can serve as proof of this passive protection. It is the rest of a board with a thickness of 55 mm, glued from four layers of high-quality tempered glass. Its perfect transparency was ensured by the use of foil glue to connect individual glass plates of different thicknesses.
A fragment with dimensions of 210 x 170 x 55 mm and a weight of 1.6 kg was found together with other parts of the Me 323 in quarries under Skuteč Airport. Several Gigants were supposed to end up at this airport in 1945, which were gradually dismantled and disposed of by local residents. It then entered the VHÚ collection in 1998.
