My favorite Air Fighters feature from back in the day is the Iron Ace. Why?
He was constantly doing stuff like this.
Apparently, the artist had both a knack for and a desire to draw mid-air collisions. It seems to just be his thing.
And so in Air Fighters #11, the Nazis build an indestructible rocket plane shaped (and used) like a giant boomerang.
They even had to fire it out of a little moving shack which was designed to catch it. (Naturally, it was defeated by destroying the shack, although not before the plane killed some poor Dutch boy's father and his dog. And no, I'm not making this up.)
