Eyewitnesses can be unreliable and all, but in the Marty Martinez interview recording on CNN he describes a sequence of three events separated by several seconds each: an initial explosion sound, then oxygen masks deploying, and then the window exploding -- which he witnessed fro just two rows away.
Not sure if that reveals anything meaningful -- engine/cowl pieces could have come loose on a delay due to the outside airflow, or the window could have still been struck immediately but taken a few seconds to fully fail -- but I hadn't seen that bit about the sequence mentioned here before.
Question: is it concerning that passengers / cabin crew repeatedly tried to plug the hole with various objects that kept getting sucked out the window? What are the odds those objects could widen the hole further, or strike control surfaces on the tail?
