All those instances where not everybody - but some - made it out of a plane that caught fire but where the passenger cabin was otherwise intact, physically allowing the evacuation of conscious passengers. Here's a good example because it has a clear cutoff point: "Less than 90 seconds after touchdown, the interior of the plane flashed over and ignited, killing the remaining 23 passengers on board, who died from smoke inhalation and burns from the flash fire." https://en.wikipedia.org/wiki/Air_Canada_Flight_797 https://en.wikipedia.org/wiki/Air_Canada_Flight_797 It seems obvious that a faster evacuation would have saved more people and a slower one less, roughly proportional to speed of evacuation.
