That video claims that "the model jet engine is a scaled down version of the real thing. It is essentially the same technology that lifts enormous aircraft into the sky." This couldn't be anymore further from the truth. Watch this video and tell me that they are "essentially the same technology:"

What struck me on the models is that the most vital components, the fan and compressor blades, are manufactured out of aluminum. Aluminum is not a high temperature metal. One pilot who had multiple start failures of these jets told me that ONE problem was the clearance between the fan blades and the housing, which must be tight to begin with for the jet to work. The shear number of failures I have personally heard of convinced me that I would not a jet sustainer.

So these small jets are at about the same level of development and reliability as some of our gliding electronics? ;-).
