The guys who "held the line" in 1942 were
ALL heroes. I agree as well.
A video well worth the time to watch.

A P-40 Kittyhawk (75 Squadron I believe) at Milne Bay in September 1942.
Below is a bit of history from the attacks on the dates listed.
April 24, 1942
In the morning, twelve A6M2 Zeros of the Tainan Kokutai attack Port Moresby, six dog fighting with RAAF 75 Squadron P-40 Kittyhawks and six attacking other aircraft and bombers. They claimed nine shot down (five P-40s, one P-39, two B-26s) and damaged a PBY. In fact, they destroyed two B-26s [one is B-26 "Hell's Angel" 40-1448]. Also, PBY A24-5 moored in Fairfax Harbor, and three P-40E Kittyhawks from 75 Squadron were shot down: P-40 A29-43 (Channon, KIA) and P-40E A29-9 (Les Jackson, survived) and P-40E A29-76 (Crawford, survived).
April 25, 1942
Fifteen A6M2 Zeros fly a fighter sweep over Port Moresby. Four strafe 7-Mile Drome. Destroyed on the ground is B-17E 41-2641.
Fortress on Mt. Obree by Bruce Hoy:
"Just after 8.00 am, with 41-2641 still stuck, fifteen Japanese Zero fighter aircrafts arrived over Port Moresby and four descended on 7-Mile drome, quickly setting a Martin B-26 Marauder on fire and seriously damaging another Marauder. 41-2641 appeared to have survived the attack until 10 minutes later, the aircraft suddenly burst into flames and was destroyed. The RAAF's No. 75 Squadron had a flight of four P-40s in the air on combat patrol and they immediately attacked the formation of Zeros, causing damage to three aircraft, and one of the P-40s receiving superficial damage in return."
