If I my  memory is correct, there has been an actual case of a small 
plane hitting  a containment building. There was no damage. Perhaps 
someone else recalls  the scenario?


Here's a note on the tests from Mechanical Engineering Magazine, June  2002:
 
"The U.S. aircraft engine tests, conducted by Sandia National Laboratories,  
slammed a 4,000-pound jet engine into a 24-inch-thick concrete wall at 240 
mph,  resulting in extensive cracking and spallation (concrete pieces on the 
inside of  the wall become dislodged and airborne), but no penetration. The same 
engine  hitting a 63-inch-thick, reinforced concrete wall, similar to a nuclear 
 containment structure, at 480 mph resulted in less damage and no  
penetration."
