Imagine that, Lonewolf_50, it would appear that only you and I received that PS/SWP/VRS/IVRS training at that little airfield at the south end of USS Enterprise Street in Milton. Those 3500 or so people between us clearly didn't, if TC is to be believed.
Apparently the 6500 or so who followed me before I started instructing it at that self-same airfield didn't get it either.
