Yes I went and watched another trailer of Red Tails on YouTube. The one I have been bombarded with on TV no less. And I found an even more interesting goof, this time on the Allied side - one of the 332nd FG's proudest moments gets changed in the film.
On 25 June 1944 on a mission into Yugoslavia men of the 332nd entered the history books. One four ship flight was reduced to a two-ship of Pruitt and Peirson. Strong winds caused them to get lost and they started to return to their airfield. Their course carried them over the Italian port of Trieste which was still held by Germans and Italian fascists loyal to Mussolini. In the harbor they spied a warship with a German cross on its funnel. Exhibiting the initiative fighter pilots are supposed to have, they dove on the warship and while wingtip to wingtip opened fire. On the second strafing pass Peirson's bullets seemed to find a mine aboard the warship that detonated. So ended the military service of TA-27, an Italian torpedo boat, that was being used by the Germans as a mine-layer. The 332nd became the only USAAF unit to be officially credited with sinking a ship.
So what is the goof in the above screenshot? Lt. Pruitt and Lt. Peirson on 25 June 1944 were not flying P-40 Warhawks. Instead the three squadrons of the 332d FG on that mission were flying Republic P-47D Thunderbolts which were more often known as Jugs. The P-47 is equipped with eight .50-caliber machine guns and the P&W R-2800 air-cooled radial engine. The P-40K Warhawk is equipped with six .50-caliber machine guns and the Allison V-1710 water-cooled inline engine.
Chalk this up as yet another reason to skip this movie. Would modeling the famous Jug in computers have broken their budget? I guess so or they thought 'no one will notice so make it more P-40s.'This sloppiness begs the question - in what other areas did the film makers play fast and loose with history?
