Are you SERIOUS?
So if I come to a PUBLIC ROADWAY that has a railroad crossing marked with just a sign, not with the lights and bars (BTW, there is just such a crossing on my way to my airport), and I roll through that crossing and get hit you are going to blame the TRAIN????? After all, me and my pickup have the RIGHT to be there, right?
How much have you had to drink before posting this? You either had too much booze or too little coffee.
There is no doubt the SUV should not have been there. There is no doubt the aircraft was ~4ft agl 20 feet before the beginning of a 400ft displaced threshold.
Only the student knows if he planned to add a bit of power and drag it to the threshold and/or the flap setting was intentional. Easy to check if the landing light works, but it could have been damaged in the incident.
If there was a way to know the outcome had the Volvo not entered the approach area I'd bet we'd be talking about a nervous student making a lousy approach after failing to properly handle landing check lists items and touching down way short of the displaced threshold.
So, I have to call it the autos fault with a poor approach contributing.
