Q20 is a bit naughty. As is whoever is feeding him the questions - did they ever track down the individual (I believe from the 5th floor) who was feeding lines, photocopied documents etc to the Daily Telegraph around about this time last year?
IMHO Mr Lancasters Q21 is the most pertinent question. Shame he is not asking, for example, how many Harrier crews are fully qualified, and current, to undertake carrier operations. If you don't have the crews qualified to fly off the decks why have carriers in the first place? I'm sure the answer would come back as 100% qualified but I suspect that would be more spin, smoke and mirrors etc.
Where is our well informed HARRIERPILOTWALT (or whatever he called himself) when you need an answer!
