ULAS 1985-1986, being a speccy was not going Aircrew anyway, but got a few hours with Mike Blee in a Bulldog. I was airsick almost every trip, and I can't honestly remember if Mike told me I wasn't any good or I worked out myself I wasn't any good. Eitherway, didn't get any more flying.
If the subject ever came up in conversation, my answer was always "I just wasn't good enough". Unlike some peaches I have heard from people who evidently didn't cope with being fallible.
Fast forward 20 years and the missus gets me a flying school gift voucher, PPL, CPL, FIC with Patt Plunkett at On-Track, 1000 odd hours later and no airsickness.
Trouble is, not enough work to stay current (1-2 hours a fortnight), so voluntarily off flying until instruction work picks up.
In raw ability, capacity, spatial awareness etc, I'd never have made QSP. But knowing that , helps my judgement, which in some way make up for my average flying skills.
cheers!
