Mister,
If you a trainer and you say you don't trust your FOs because the training dept (yourself?), I agree with my fellow pilot, please get out of the training department or retire. It is people like you that MM said he would get rid of. Some of the FOs here have more experience than you will ever have. You are a joke and good job on starting a bad chain of replys and bad feelings when we already have enough problems here.
