I'll fight you for any 1/72 pilots!
Why Airfix (or someone else) doesn't realise there's a massive market for a box of mixed pilots I don't know....
There's the Revell sets for RAF and Luftwffe, but they're expensive for the number of usable pilots you get, and the RAF men are Giants Among Men, and rarely fit the 1/72 cockpits.
Then there's the Hobby Master sets - the US WWII pilots are OK, but the other WWII and Jet pilots are dreadful.
Airfix already has lovely molds for a whole bunch of them, it wouldn't take much to punch out a box of them - you could get up to 10 WWI, 10 WWII, 10 Post-War, 10 Cold War and 10 Modern in a single sprue.
