It's the seesaw of life. Once it shifted to one side it takes a lot of effort to make it come up and fall on the other side.
It's quite stable once on ground on either side!
At the moment it's steady on the dirty side. Who would want to go there? Maybe mudwrestlers.
On the other hand I know of at least two guys who were not considered for training who would bring in some competence and a lot of aviation common sense.
But I guess that was the very reason for the rejection which points to some more serious problems in training than the dire T&C's.
