Sammy Mason's _Stalls, Spins, and Safety_ provides interesting insights into the dynamics of spins, inverted spins, and flat spins. The observation of little damage has been found in other flat spin incidents. Because of the speeds and attitude of the plane, the energy of the impact can be absorbed by the airframe. The plane ends up being squashed, but the occupants don't. -- Alan M. Marcum Fortune Systems, Redwood City, California ...!{ihnp4, ucbvax!amd, hpda, sri-unix, harpo}!fortune!rhino!marcum
