The whole catastrophe occurred in about 30 seconds
It would not take a very large explosion if it occurred in center baggage area where fuel lines feed the engines, so one pilot posted. All they needed was one IS guy in the baggage loading section who knew what he was doing.
Egypt said there was no mayday , perhaps the pilots were dealing with some technical issues before the "explosion " occurred when the aircraft reached cruising altitude - 2 different issues?
“Reports read indicate both engines were burning at 28k feet “
