Wow that's ballsy after take-off!!
It paid off in that case.
As with Concord the fact of heavily on fire certainly had a high probability on not ending well for all on board. Only with luck not more than 4 people were not killed (6 others injured with burns I assume) in the hotel it crashed.
I don't recall the 747, but the pilot at 150kt was committed to take regardless even though the upper speed of V1 from memory was 164 kt (11 kt over then if upper limit used).
