Oh I know block time is something completely different, as I say I have done it before in 30 minutes with a block of 55. Ryanair seem to extend their scheduled times, which I am sure is what helps their on time performance, added to the small airport etc.
Anyway, I just thought 27 minutes in the two biggest airspaces in the UK (All London airports and Manchester, Liverpool etc.) I thought it may have taken slightly longer. It look nearly as long from taxi (18:11) to take-off (18:32)!
