This is my favorite discussion...so I like keeping it alive.
Vulching is the fine art of killing an enemy on the runway, usually during take off, but could be landing.
Vulching is villified by some, practiced by many.
My opinion is based, at least partly, on history. Many planes were shot on the runway, taking off, or landing. Probably most air to air kills on Me262s were when they were caught low and slow on landing.
I see nothing wrong with vulching. If you want to upped at a capped base, you deserve what you get, pure and simple.
The notion of chivalrous combat went out in WW1. Douglas Bader (DFC, etc, 22 kills with no legs) said, "It's not a bloody game of cricket". What he meant was, it's our job to kill the enemy, not play at sport.
Up a capped field? Die as expected, but stop crying about it.
