PTF is an interesting topic and one that is raging in 2 other thread right now:

With PTF rife in the airlines it was always going to be only a matter of time before it hits other areas and is exploited, in this case by MH and through his VE facade. Others could well follow. The GA sector could be next making PTF universal throughout the industry.
There are some interesting points made in both of the above threads and suggested actions to prevent it spreading.
