isn't a rock, pick it up." They were asked to look out particularly for items which might be charred and which might therefore have been close to an explosion. British military helicopters flew over the crash site, pointing out large pieces of wreckage to the search parties. Private helicopters, equipped with thermographic cameras, were drafted in to survey the heavily wooded areas surrounding Lockerbie. Within hours of the crash, photographs of the area taken by a French satellite were delivered to the investigators. High-resolution photographs from spy satellites were also provided by the United States Department of Defense and National Aeronautics and Space Administration. Every item picked up was tagged, placed in a clear plastic bag, labelled and taken to the gymnasium of a local school, where everything was X-rayed and checked for explosive residue with a gas chromatograph, after which the information was entered into the Home Office Large Major Enquiry System. Reconstruction of the aircraft and luggage containers All parts of the recovered aircraft were taken initially to a hangar at Longtown, Cumbria, where they were examined by investigators from Britain's AAIB; they were then moved to the AAIB's headquarters at Farnborough Airfield in Hampshire for the fuselage of the Boeing 747 to be partially reconstructed. Investigators found an area on the left side of the lower fuselage in the forward cargo hold, directly under the aircraft's navigation and communications systems, where a small section of about square had been completely shattered, with signs of pitting and sooting. The fuselage skin had been bent and torn back in a so-called starburst pattern—petalled outwards—a pattern that was evidence of an explosion. The forward cargo hold had been loaded with capacity baggage containers, made either of fiberglass or aluminium, and filled with suitcases. After the explosion, most of these containers showed damage consistent with a fall from , but two of them—metal container AVE4041 and fibre container AVN7511—showed unusual damage. From the loading plan, investigators saw that AVE4041 had been situated inboard of, and slightly above, the starburst-patterned hole in the fuselage, with AVN7511 right next to it. The reconstruction of container AVE4041 showed blackening, pitting, and severe damage to the floor panel and other areas, indicating that what the investigators called a "high-energy event" had taken place inside it. Though the floor of the container was damaged, there was no blackening or pitting of it. From this, and the
