You agree that what was unlikely? Engine failure?? Not applicable to AF447.
AF447 went from cruising altitude to impact in just 3 1/2 minutes. During that time the crew were rather to busy trying to work out what was going wrong to make any calls.
An engine problem such as fuel starvation (for example) wouldn't have downed MH370 that quickly. I reckon they could have glided for 20-30 minutes which would have given them plenty of time to put out a Mayday. The fact they didn't do so suggests that whatever happened was either immediately catastrophic or quickly became so. Beyond that, I wouldn't like to speculate.
