Pardon my rampant ignorance, but what does an SAC(T) do on a C-17? Ground Engineer I can understand, but what does the (T) do please? I'm not digging at Joe (don't know him from Adam), I'm just genuinely intrigued as to what the role is. More, please!
He is basically the GE's 'biatch'. Large types (Vicky 10, Tri* C17) tend to take an additional mechanic to assist the GE when down route.
