When Air Force Reserve Col. Keith Knudson, left, commander of the 419th Fighter Wing, was diagnosed with kidney failure last year, his active duty counterpart, Col. Scott Long, commander of the 388th FW, volunteered to donate a kidney of his own. As part of their duties at Hill Air Force Base, Utah, Long and Knudson have worked closely on how best to capitalize on their shared equipment and facilities. Now they may soon be sharing a kidney.
