If you heard a pop, it means the tube was outside the tire when it burst. A tube may deflate suddenly, but it can't make a loud bang or pop as long as it is contained. The most usual explanation for this type of failure is the tube working its way outside the bead and then bursting. Without the tire, the tube isn't strong enough to contain the high pressure. The most usual explanation for this is the tube was caught between the bead of the tire and the rim and eventually worked its way out. Depending on how the tire was installed, this can happen right away or after several miles.

By the way, it doesn't make sense to look at how a tubular would handle this situation since this type of failure can't happen with tubulars.
