First time I was really sick was in a VC
-10 on a training flight from Brize Norton, doing circuits and bumps around Fairford. It was empty, no seats other than a row right aft. I was sick as a pig from start to finish. 3 1/2hrs
I was ill again on a Nimrod flight arranged by my wife for my 40th birthday. Spent the whole flight holding my head in the galley - another 3 1/2 hours, this time low level around the Moray Firth.
I got my revenge though. Sent her up in a glider flown by my boss. As he dumped the tow line he looped it - frightened the crap out of her
Strangely enough, I was sick in a C-130 when we landed at Incerlik from Cyprus. Mind you, that had something to do with being on the piss from 6pm to 3am and then getting up at 7am to fly at 8.30.
Anyway, not something I am proud of but, sick happens
