basically, just like the eny list for the planes giving different numbers of perks, there is an obj for bombers. if you fly something with a high obj (like a ju88 or a stuka) you will get tons of perks. ive had 65 runs that took me 5 minutes in ju88. just bomb the entire town, or all the factories at a strat, and you'll get loads. and like OOZ said, base captures often get you over 30 perks. perks aint everything tho

those 234's really suck, they carry no ord (like 3k lbs) and no defensive guns, and arent as fast as you'd think. a tempest, typhie, 109g10, and those thing will all catch it in a shallow dive. and if someone sees you (enemy), they just up 262's and come kill you

perk planes are boring in my opinion, because everyone wants to kill you, you cant have a good fight
hey ho, my $.02
