I’m hearing the BATF is there working with the NTSB. Is that usual?
Pieces of the A/C were found away from the crash main impact.
Some are saying the A/C broke up in flight, possibly a bomb aboard?.......................
From the FAA website
“ The Bureau of Alcohol, Tobacco, Firearms and Explosives (BATF or ATF) does not typically investigate plane crashes. The National Transportation Safety Board (NTSB) is the primary agency responsible for investigating civil transportation accidents, including plane crashes, in the United States. If a plane crash involves criminal activity, such as the use of explosives or firearms, the ATF may become involved to assist in the investigation. However, for a standard plane crash, the NTSB would lead the investigation.”
I don’t think so unless explosion. Is being considered.
I believe so.
OTOH, aircraft blowing up in the air is unusual.
Me? I think, based on one data point, an oxygen cylinder being found a mile from the impact site, and my wild butt guess at a scenario, that it was a larger cylinder than just an under the gurney one, but was large enough to last the entire flight.
That cylinder broke loose, fell and snapped the valve stem, launching it on a path of destruction through the interior of the airplane, flooding it with pure oxygen, shredding the electrical system, and possibly lancing through a fuel tank.
Pure oxygen, aviation fuel (or even just the organics inside the passenger compartment), and electrical sparks. Not a good combo.
Result? Midair boom, as recorded on a Ring camera, and a fireball falling to earth.
