Yes pressure cookers do explode, but there is a blow out valve in any made in the last 50 years that will rupture at about 25 PSI. Modern pressure cookers are designed that the gasket will fail long before the metal and even if all the safety features fail, the pressure at rupture would be around 3 atmospheres, not enough to cause a very serious explosion. You, it might dent your stove or spread crap all over the kitchen, but the risk is more from scalding than from flying metal.
The point is there are 3 redundant features that should prevent an explosion. You have to just about weld the steam vent closed, plug the safely valve and epoxy the lid in place on a modern pressure cooker to cause failure.
