fire system les was describing deployed wasn t able to exting wish the fire. it appears that the fire was externa external. there is a point in takeoff. the plane cannot stop. it has to go up in the air. correct. we focus on three speed. let me focus on the main one, v-1, the decision speed. at that speed if we make the decision to stop the airplane, stop the jet, stop the threat. at that point if we have made the decision prior to reaching the speed there should be enough runway at the weight we re at, at the temperature we are at, altitude we are at to stop the airplane. in this particular case in las vegas, very hot that evening. 100 degrees. looked at 7:00 in the evening. approximately 3,000, 4,000 feet if i recall on the elevation, lot of performance there. the airplane should have came to a stop. and as we saw it did very well.
