Planning a commemorative event 11 years in the future when it's only 89 years old? Hmm...
By extrapolation, the Army needs start planning its 400 year anniversary in 2061 around 2012. The Navy has already missed the boat to spend the same proportion planning its 500 year anniversary in 2045.
I'm sure some bright spark of a politician would try and spin this that RAF are ahead of the game, the Army looking good if they get their act together in the next couple of years and the Navy are crap, and therefore need to be reduced in size.
