Well the wing was also touching the floor, for all the cabin crew know it could be a fuel leak, possible fire . . . .many different things, we are not pilots. But that is clearly a wing down attitude. And if i was flying i would of got off my jump seat and open my door. One thing i will say about FR is that it always puts safety first.
On a different note, i still wonder why the crew of the clr-lig crew didnt jump with the pax.
