A little excerpt from an article on Soviet flown P-40's (http://lend-lease.ai.../p-40/index.htm):
"The first batch of Tomahawks from the USA was sent to the USSR in September 1941. This shipment was purchased for gold and was not part of the Lend-Lease program..."
There's a long and detailed history regarding the P-40 and it's involvement with Soviet air forces.
I haven't seen or heard anyone mention the P-40 being included in the (wish)list of aircraft for BoS. According to all the Googling I've done, I've found various pieces of information that would place many P-40 variants on the front lines of the Russian air war during the Battle of Stalingrad.
Has anything been hinted at including the P-40? Is there a demand for the P-40? It's one of my favorite aircraft of the era, I'm hoping it makes it into the game.
