If the counter is counting down, then it’s around the 3:03 – 2:53 mark.
As you may notice in the video, Bush’s wrist watch dropped at some point, but it has been confirmed that it was found by the bodyguards who handed it over to Lady Bush later on. And you will see in many other videos Bush wearing his watch again while entering Air Force One during departure as he waives back to us. If he had a spare watch, most likely it would have been inside the airplane, therefore, there is no doubt that Bush got his original watch back and everything was accidental. So, don’t worry, be happy, time is still ticking on and everything is in Bush’s hands!
