I did read the figure of 630 in a newspaper - so no guarantee that its accurate. It could have been the number of jet pilots, not including helicopters etc ? :-/
Nige - I understand that many support staff are needed, but it sounds quite top heavy to me. 
It does to most ... until you see the scale of a military operation. If you were to be unfortunate enough to visit Camp Bastion for example... the number of aircrew there is miniscule compare to the total number required to get the job done.
We once had a TV crew travel with us on a Herc (Gulf War 1) who watched the whole prep of a trip and were pretty impressed by everything, especialy some of the finely balanced fuel/weight calculations we were doing .... until they got on board.. and all they saw was 6 pallets being strapped down. The load was only 2 ft high and the "back end" looked empty.......
Que the scathing "what are we wasting our time with this for" .. until it was pointed out that without those 6 pallets all the tornados might as well not be in theatre. It was also pointed out that 6 pallets of 1000lb bombs is one hell of a load and was near (

) the maximum capacity of the aircraft.
The fact that the fast jet boys would use them all up in one night mean't we Herc boys were busy and knackered for many weeks .. but no headlines in the papers for us ..
Support, Save, Supply - Station motto for many a year ..

and it continues even now ..
