Status Report 3: If I am reading these posts correctly, here are the leaders in kills after only ONE sortie (NO rearm, NO refuel, fighter only):
AHGOD, Chog, 42
Wulfie, P-47D30, 26
Furball, Chog, 26
Citabria, Me262, 25
Gatso, Chog, 25
Ack-Ack, P-38L, 24
Eskimo2, Chog, 24
Icemaw, P-47D30, 24
Load, 190A8, 24
NHattila, P-38, 24
Steve, P-51D, 21
Skurj, 110G2, 20
Slash27, La5, 20
These 13 the only pilots reporting 20 or more kills, and only their highest single total score is mentioned (some also have other sorties above 20). Let me know any corrections needed.
Chogs are four of the top seven, including first and tied for second, third, and fourth. Wasn't Chog the aircraft that started the clamor for perks? Most aircraft are heavy firepower or good endurance or both.
