It'a daft isn't it? I thought he was talking about U2's pilots! They're rich enough to have a personal fleet of them! Why use ridiculous abbreviations like that in an industry riven by acronyms as it is! (IMHO!). Being clever? I'v e only been a professional pilot for over 40 years in the UK and I didn't know what it was. I'm beginning to wish I didn't now.
