Then I invite you to re-read the final report, which concluded:
-The excess mass (about 800kg) had no significant effect on the T/O distance / stop distance
-The wind was in fact light and variable (contrary to what ATC said)
so I don't know how you concluded that they took off with a tailwind
-The FE did shut down the engine that had to be shut down (#2)
Thrust on #3 and #4 was volontary reduced (by whom? I don't have time to check if it's in the report)
Nowhere in the report is stated that the FE doomed the aircraft
It's even mentioned that had all the engines been working properly, the result would have probably been the same given the fire that was spreading quickly (have you seen the pictures just after take-off? They had no chance to survive that)
On a side note, comparing the number of accidents at AF, which has thousands of flights a week, with Buffalo's is quite laughable...
