Apparently the major fire didn't start immediately upon impact, as some early reports suggested. I didn't see how everyone could get out if there was an immediate explosion or major fire with a lot of smoke. But I can see how most everyone got out if there was a few minute delay before all the smoke and fire. However, I still don't see how they accounted for everyone so quickly.
Being reported pretty widely now...it's pretty unbelievable that everyone got out of this...
