Evacuation
Of course paseengers will always think it took too long to get out. Yes they probably DID see smoke/ flames before the crew as their windows are bigger and more numerous than crew portholes in the doors. Passengers would have seen the flames and wanted to get out immediately, but bear in mind that cabin crew have to wait until the aircraft has stopped and engines switched off until an evac can be started, otherwise passengers end up evacuating straight into running engines.
Everyone got out ok in this incident. There is little point in saying "it could have been faster"
It really is a great example showing why window blinds should be kept open for all take offs and landings.
