Reminds me of my favorite line in the US Antarctic Program Field manual: 18.1i Crossing Crevasses ... If a snowmobile or sled starts to break through a snowbridge, experience and circumstances will dictate whether to brake and attempt to hold the fall, or continue driving forward in hopes of getting across before a catastrophic collapse of the snowbridge. In either case, a change of underwear is recommended.
