Doesn't explain why they would wait to detonate ex-CDG vs ex-CAI. Not buying it without a better explanation.
I figured this question was coming next.
There are a bunch of reasons why that could be. The components could only be properly put in place by an actual crew member who was to important and crucial and unwilling to die but was off duty on that return leg and was replaced by another crew.
Im done with my conspiracies, I'll wait till they have something more conclusive.
