Survival of object in impacts like 11, 175, 77, and 93 is possible and has happen in accidents with greater impact energy. I have been at accidents where the cockpit is buried deep in the ground, but instruments were ejected as the cockpit was smashed into the ground due to it's own energy/speed. Buried cockpit, ejected instrument in perfect condition. No blown up plane, intact plane hits ground. Photos from pilot, checklists, no prior breakup, these things survived the impacts in the plane and survived during the 0.2 second impact.
Reheat flew fighters; this is kind of very personal, he shares the facts with you.
If anyone thinks the survival of objects in aircraft impacts is strange or can not happen, they are wrong (WRONG). There are no objects on 9/11 that were found that could not have survived.
I have been trained in accident investigation and survival of objects happen. Listen carefully, even in the worse accidents of aircraft and all the impacts of 9/11, things can survive. If you want to think of the worse possible accident with objects surviving, think shuttle accident; I see no way things could survive but my accident investigation say yes, and the FACTS say yes, things survive.
But for 9/11 truth disrespectful dolts, facts are not used, science and knowledge are rejected and lies rule! Believe reality, or believe the lies of 9/11 truth; it is self critiquing and ignorance for the latter. Only 9/11 truth is unable to find facts and understand evidence. Why do they lie?
