Great find. Dreadful reporting....as usual.
"The Germans initially intended to use the plane in the planned invasion of Britain, Operation Sea Lion"
They'd have needed a time machine since Messerschmitt only submitted plans for the powered version of the Me 321 glider,which became the Me 323,in the autumn of 1941. Series manufacture started at Leipheim and Obertraubling in the summer of 1942 at which time the Luftwaffe obviously contacted Dr Who.
