As a current student at IFTA I can tell you that the Gound School instructor IS NOT leaving the school...
I'm one of the socalled 8 danes, and right now doing the second module on the ATPL's...
So far I have done my JAA PPL and my FAA IR at the school, and is has taken more time than they promised me from the start, but I cannot complain about the quality... Expecially the american Instructor Randy is good...
I think you have to be careful about these kinds of forums, because you never know, who is writing in here... So get in touch with current students before making any decisions....
Happy flying out there and good luck to you all!!!!
