''Reading the threads here you'll find lots of pilots who dream of flying KC-10's or KC-135's, tanker planes!''
A common misconception is that tankers always have a lot of fuel. It's true that they usually have a lot of fuel when they take off, but a tanker pilot's perfect trip is to get airborne with 80 tonnes and land three hours later on fumes. Their job is to give it away and will usually oblige a fighter who wan't just a little bit extra. I flew tankers for about ten years and always tell my FOs that I won't be offended if they insist on carrying a bit more fuel.
Beware of ex-tanker pilots - they think nothing of landing on minimums!
