Strange that looking at the members of the Board of the CAA only four of them seem to have any experience of aviation, the rest being the usual political appointees and Chaired by Dame Diedre Hutton, whose 'expertise' seems to be in food and is now on her 11th quango.
Looking at the job specification I see that 'The Chair will receive remuneration in the region of £130,000 per annum for a two day-per-week time commitment.'
Nice 'work' if you can get it!
