ShaunLanc,
That info is not quite right. Kwb911 is correct.
Very few cadets have got other forms of flying jobs, largely because it is very hard to find any flying job at all. I'm sure a handful have become FIs and I even did some glider towing myself (but unpaid), but for the vast majority it's a job at tescos or whatever if they've not got some periodic flexicrew work.
I'm sure many in the holdpool wouldn't turn their nose up at such flying but it's just so hard to find anything, like Kash360 showed us with his trip to Maun (good luck btw Kash, u deserve to succeed).
