Skippers were going to pull out of Kooly before the conquest incident as they lost the contract to XR (what Icarus alluded to) who could provide bigger aeroplanes than what could Skippers.
Skipper's problem seems to be lack of aeroplanes and more so the pilots to fly them. I've been told from someone who knows, skippers have no problems with keeping their engineering department staffed. Getting around 3x more than the average pilot there +overtime/etc is probably why.
That's what I've heard anyway.
