I had a thermostat fail 30 years ago in a traffic jam, and the coolant just boiled and barfed out of the overflow tank. When the 'stat fails shut, the steam builds in the heads rapidly. If the pressure got high enough, I'm not surprised both hoses popped off. Hose clamps these days are not what they used to be. But, for you that's better than blowing out a freeze plug or splitting the radiator.
