A few unrelated points:
Pax evacuating with bags:
In this type of incident, are there arrangements for re-uniting surviving pax with their surviving hand baggage and checked baggage? Understand it will be low priority, and after forensic NTSB investigation.
The overall robustness of the airframe is impressive. Would a composite airframe perform as well?
A bit of confusion in the posts about VFR, CAVOK and VMC.
