It was already reported that the tire blew on landing, not taxiing. Big difference when the reports also said the front tire blew when it came into contact with the runway, before the reversers are activated. It would have been leaked out by anyone riding on that plane that he stood up while it was in the process of getting all the wheels on the ground.
To add even more against that notion, what would have been gained by getting up before it even gets close to the terminal, especially if he was in first class?
Why do any of these people jump up and start messing with their things in the overhead bin, only to stand there, crouched under the bin, while the aircraft comes to a complete stop and the doors are opened?
