As for lance, I think a crappy glue job is possible, but another thing to think about is that if he was going 40 mph, he was probably on the brakes a decent amount, heating up the rim and tubular glue. This could have contributed to the tire rolling off. I didn't see the crash, so I don't know what happened exactly though.
Doubtful. You don't get up to 40 miles an hour on the flats by using the brakes hard. On the flats, you may feather your front occasionally, if at all. Usually, a rim will heat up enough to melt glue only one very twisty fast down hills, where you have to brake very hard for the corners.
