I think most of the people going for these schemes are pretty desperate.
They are probably at their wits end because thay have nowhere to turn due to the fact that they are not good pilot material. It probably looks like a short cut to bypassing the selection process.
The reson why airlines havn`t chosen these guys is probably simply that they dont fit the profile of pilots that they employ.
Just because you have an ATPL doesnt mean your going to make a good pilot.
Try bettering yourself as a person before trying to shortcut the whole thing otherwise it could go tits up a bit further down the line.
