A.P. Firstly, I have NEVER heard of an engineer doing that. You admit yourself it was heresay anyway. Ultimately, the dispatcher's final task before push is to ensure all external doors, hatches etc are closed. He has the wherewithal to do so. So how that is going to delay a flight is a bit hard to figure. I know you hate VA, and I agree with some of what you have to say, but sometimes dude, have a think before you post utter crap.
