Bearing in mind I am not the fastest swimmer in the pool, but isn't it true that if a pilot takes off in a plane, and brings it back without crashing it, that pilot did in fact land the plane?
I cannot recall any stories of Bush crashing every time (if at all) he flew, so that story of not being able to land must not be true.
The cheeto dust must have clouded some of their thinking.
edited to add: just nadined, and could find nothing regarding G. Bush crashing any aircraft either during pilot training, or after he completed that pilot training during the rest of the time he was part of the ANG.
There is also nothing at this other very informative site
http://www.electstevedawes.com/ but there is much there to read.
