Plane crashed due to losing altitude although it seemed under control (not stalled)
RAT deployed which happens either 1) manually or 2) There's loss of power (below idle basically) from both engines
Everything else is people making up far fetched stories.
Vapor lock for example makes zero sense. The fuel when pumped into the plane is actually 'cool'. Even though the outside temps were 40-43 celsius, how long would it take for many thousands of gallons of cool fuel in tanks to heat up through surface conduction? Very likely, a very long time. It's not like the fuel was being boiled or had a heat exchange mechanism with the ambient air.
