"complete failure" ... whatever.
109's and 190s were pwning plenty:
1) Eastern front vs Russia flying Russian and USA aircraft.
2) Southern front vs USA in Italy. (Tuskegees for example)
3) Western front vs USA bombers in the air.
Three out of four isn't bad, considering USA - the 'arsenal of democracy, USA out of it, England would've been porked.
USA pilots and crews fighting at the Russian front vs Germany.
1) While on the topic, USA flying from North Africa to Axis held Romania, oil fields. (usa pilots eastern front)
2) Hartman's interview speaks of USA p51's with USA pilots doing missions on the eastern front.
3) Some incident also of USA bombers and pilots 'accidentally' bombing russian troops ticking off stalin... (my guess was just to show Russia what the USA could do.)
Yep, whatever.
