Name recognition in popular vote.
They've heard about the He-111..... they've seen a movie once. Cockpit reminds them of the Millenium Falcon. It looks "cool" --- never mind it's hey-day was the Spanish Civil War. At least BoB senerio gets an addition.
It will come down to the B-25, He-111 and maybe the Yak 3. I have doubts about the P-39 now, since the mid-war G.55 got early cut.
