In my 40 plus years in flying predominantly in the airlines and in a training capacity…yes there are some really bad TREs and TRIs and confusingly a lot of very good ones. If VS, one of my former employers was one of those that concocted a sim failure presumably with the cooperation of the TRE then they should be ashamed of themselves. Very disappointing. There are always those with the larger egos who use training appointments as a stepping stone to management. Most don’t know why but it is just ego and ambition. Unfortunately the amoral among that group do not care about collateral damage.
