Well not actually the first, but the first in quiet some time. a small squadron of orks went up against imperial thunderbolts and a marauder bomber. bomber intercept mission. sadly, it was destruction for me but still, i learned that the orks are lethal at close range were as the imperials excel at meduim range. the ork plans are capable of pulling some surprising manoeurves (particularly the fighter bomber) were as the imperial thunderbolt is a tough little fighter and the marauder can soak up the hits.
speed and timing are the key but too much speed and you fly right off the table.
