Incorrect goof

I have not seen the film but the trailer clearly shows that the aircraft in question are converted bombers and not poorly CGI'd C47s. Whoever listed that as a goof obviously doesn't know much about the history of airborne forces. A great many jumped from converted bombers through a hole in the floor. This you can clearly see them doing in the trailer. I know for a fact that C Coy, 1 Canadian Para Bn jumped from Albermale bombers (from Dan Hartigen's book "A Rising of Courage". Hartigen als mentions that the Coy Commander bribed the crews to drop them earlier as he was afraid of not having time to secure the DZ for the later sticks. This makes C Coy, 1 Cdn Para the first allies to land in occupied France (aside from SAS distraction tms dropped near Calais and some pathfinders). They technically even beat Maj Howard's coy in their glider assault on Pegasus Bridge.
