Great job by the crew all round - especially the FA at door L2.
Some have commented that it's a good job it didn't happen after V1 - and I agree, much better to be dealing with problems stationary on the ground. But not because of the fuselage damage that resulted.
I think that the damage to the fuselage only happened because it was stationary on the ground. They were taking off on 07L and the wind was 360 at 5. The prevailing wind was blowing the fire from the left engine directly against the fuselage. If they were airborne, the fire would be streaming aft, along, through and behind the engine. You wouldn't have the same fuselage damage, if any at all. Of course they would probably have a different set of problems to deal with, particularly if the fire was uncontained.
