Low Time Students
I thank you all for your comments; it did help me and also drew my attention to some facts that were unknown to me; I must admit like Parallax effect on students. I remember that during my initial instructor training; I never thought that it would affect the student! I think this was a big mistake which led to an expensive learning experience
I must also say that I am disappointed with the controllers here. Sometimes they line up GA immediately after a landing 737 and in less than a minute; you are cleared for take-off. As I have close to 12000 foot runway; I roll the plane down on low power setting till it passes the point where the 737 vacated the runway, hoping to clear the wake turbulence.
I agree that the student hit the vortices; but I also think that it was not a fully contributing factor
Thanks a lot for your comments once again
