I'm for a more radical approach:
1) You die, you lose all points gained while flying that sortie prior to your death.
2) At the end of the tour pilots are ranked by their best kill streak, all other sorties with lesser kills are ignored.
Chutes are unkillable when:
1) they bail under 1K
2) they ".ef" under 30 seconds after landing.
This eliminates the problem of chutes being spies, and of idiots getting chute kills.
People are paying 30 bucks to fly air quake? Cool... well I'm also paying the exact same ammount to fly a WWII sim...
