Inspector Cleusot of the Surete would begin his investigations in Miami which of course in the common denominator in both of these outrages.
In past times of labor unrest in Miami, suspicious maintenance 'failures' have occurred.
Evac slides mysteriously popped at Eastern and wires were cut in the weeks before the IAM strike. Seems like the mechanics were given the day off in the hours before the strike deadline lest they trash the place on the way out.
Of course, maintenance outsourcing in MIA has also had horrific consequences in the Valujet 592 crash.
It will be interesting to see where the investigation leads in these 'unusual' seat incidents.
