I know this has been done before, but I thought I would share my version of a plane collision chart indicating where planes with differing climb rates would colide based on the approximate height that they would be at.
The 'No climb counters or ANY climb counters' rule is fine for basic play, but when you get beyond that it's silly that a climb rate 4 plane with 1 climb counter would colide with a climb rate 4 plane with 3 climb counters. Hence the table for quick resolution during game play.
There's also a copy in my photo album
