Learjet has a strong structure
 

I hate to see interesting aviation anecdotes disappear forever. On someone's blog, they were talking about the structural integrity of the Learjet fuselage.....

"After the Payne Stewart Lear crashed up North, the first media speculation was some kind of structural failure. I managed the test program on the Lear 23 and we pressurized the fuselage (with water) to 21.5 psi. The structure was so strong it failed my test rigs several times. We broke the airplane only once. A structural failure? No way!"
