My comments are fact based on just one person ,and this person, at one time almost took out pit row! a well placed barrier stopped the plane at the last moment ,if you were their you would be looking at the waiver system totally different! Lets face it the best training is by ducted fan....(but allot of the same comments are heard over and over that its to exspensive to put one toghther just for a waiver, it took me 3 DF jets to finnaly get good enough to fly it anyway the cd asked ,lost a couple in trainning I dont think this excuse would hold up in court!) Lets push the topic a little further and lets for see what were trying to avoid with the waiver system! And that would be loss of life or limb,loss of flying sites,loss of equipment (aircraft).Again I'm not saying if you fly a prop job you wont be-able to fly a turbine safely ,just I believe you can't substitute training with a jet, with a prop driven aircraft.... try and rent a real jet and show them your log book with a 1000 hours in a 172.. I know of only one place that will allow this and thats the Microsoft professional flight simulator...
