The Focke-Wulf-190 was an excellent single-seat German fighter during WWII. It has a large 14 cylinder BMW radial engine unlike most European fighters, which had V-style water-cooled engines, with the exception of the P-47, which had the 18 cylinder radial Pratt & Whitney R-2800.
What I didn't know is that there is a compartment in the fuselage large enough to fit a second
person. It was actually used in this capacity when the squadron had to move to a forward base quickly, the mechanic could ride in the back so that the planes could be
armed and maintained quickly at the new airfield. The space wasn't that big and they essentially had to lay down against the aircraft's master compass.
During D-day in June 1944, the Luftwaffe tried to stop the invasion, but with the Allies having launched 13,000 sorties in just one day, they had no hope of competing. Several air wings located in northern and southern France tried to make it to airfields in range of the landing beaches to reinforce those already in the area. They took their mechanics with them, stuffed in the back. Their Ju-52 Tri-motors were usually used for hauling parts and mechanics around, but there wasn't any time to wait and they were more vulnerable to enemy fighters. Unfortunately, for those skilled mechanics, many of the FW-190s were shot down, with them in the back, so that just as many mechanics were killed as FW-190 pilots. Man, what a claustrophobic way to go!
You don't think of WWII fighter planes carrying passengers, so this reminded me of the AD-1 (A-1 after 1951) Skyraider, which could actually carry up to a dozen passengers on the E version. Of course, the Skyraider wasn't finished in time to fight in WWII, but it was designed and built during that time.
Those FW-190s that made it to the close-in airfields were either destroyed on the ground by strafing runs of Americans and British fighters or shot down in the air. Only a very few fighters actually made runs on the beaches. Two of them, led by Joseph Priller, a German fighter ace, were able to strafe Juno and Sword beaches and actually made it out alive. They were lucky as there wasn't any allied anti-aircraft set up yet.
The Germans tried to supply the forward bases by ground as well, but everything moving was a target for the overwhelming air presence of the allies. Most convoys didn't make it through without losing at least a few vehicles to strafing.
