Have a mate who's son is 18, joining next year. Possibly on a Sqn at 20?
Unlikely, with all the holding it's taking around 5 years to get to a Sqn, sometimes more. With the dog's breakfast that is MFTS coming in & its procuring of ac in almost negligible quantities I can't see things getting any faster or more efficient particularly if we wish to increase throughput to man all the extra ac we're 'promised'.
