The Army notes that the aircraft was used for “Government testing” and as the result of the testing, it “is not a functional plane”. They’re not kidding.
The A300 … was most likely used in “least-risk bomb location” (LRBL) testing which is used to determine where onboard an aircraft a crew would want to place an explosive if found.
By FAA regulations finalized in 2008, commercial aircraft holding more than 60 passengers or weighing more than 100,000 lb. must have a designated LRBL, a location “where a bomb or other explosive device could be placed to best protect flight-critical structures or systems from damage in case of detonation”.
