In some circumstances fat crewmen and crewgirls are what we have, we cant afford to lose them and their experience granted; that said, they are an eyesore and a blight on the service in the joint arena. It isnt just Shawbury though, there are even more of them at Lyneham and Brize - even 99 has its fair share at senior level and what about the fatigators that are abundant on the truckie fleets?
To their credit, they have the the experience and they have the enthusiasm to do the jobs in austere circumstances on the front line; there is just more of them to love. Students going through Shawbury know the difference between the civvy instructors and the mil ones - after all they arent supid - they are educated beings. Its just a shame they have let them selves go to such an extent, especially when they have a good gym at Shawbs and some fantastic running routes.
