re: 3rd party witness confirms Jefferson and Johns involvment...

A good friend of mine had a fractured vertebra in boot camp and did not even know it until a thorough physical including xrays was performed before attending jump school...I forget why they xray'd his back or if that was just S.O.P for attending jump school

that is why I asked if there were a way to tell when the injury actually happened.This happened to him just before Dessert Storm and he was allowed to finish Jump School and fight in that conflict...
