My couple of pennies:
1. Miracle anyone survived after the fire broke out, it was very intense.
2. Even if no one carried out any bags some people would have died due to the fire being so intense.
3. Bags most likely did impede the evacuation and very possibly more lives would have been saved had there been a faster evac.
4. It will take a govt mandate to reverse the current situation of larger and larger bins for larger and larger take on bags. Many airlines charge passengers to check in even one bag. No small amount either. Overhead bins should be made to be very tiny. Only very small briefcases, ladies handbags and the such should be allowed on board. We all know how much faster passengers can board and be seated if they didn't have all those bags with them. Which really don't belong in the cabin. It belongs in the cargo hold. And of course human nature dictates people will try to get their bags and take them with them. You simply can not stop this , will be like stopping the tide from coming in. Even in a full blown emergency. Physically stop them taking onboard large bags will the the only solution.
5. Looked like a fairly normal approach but hard first tire contact. After which the airplane seemed to gain some height as if intending to go around. Which is said to be the only correct thing to do after a bounce. In one of the vids it seemed the plane made hard contact , lifted off quite steeply and gained a bit of altitude then nosed down and made harder second contact after which fire could be seen.
