Simply fuel dumping via 'torching'

Answer 5

This is a picture of an F-111 Aardvark, General Dynamics made this as an American Air Force bomber. Today, the only operator of the F-111 Aardvark is the Royal Austrailian Air Force. What it is doing in this picture is a fuel dump; the dump ends just fore of the exhaust so as it dumps it gets burned up so it does not reach the ground. It is done at air shows, however, for entertainment, for (as the picture shows) it leaves a long trail of fire behind it.

Answer 6

It is known as torching.

The fine art of dumping raw fuel into the exhaust so that it burns bright and long. Remember the Colonel Ray K, he'd said that in his Ardvaark days the pilots used to do it for fun, with contests like who has the longest flame...

It doesnt have any practical purpose other than the sheer kicks and airshow wows...
