Moreover, the suggestion that someone has made a decision in this mishap to takeoff, a conscious act made when the option to not take off, or to "swerve" existed, is not in evidence. This is pure speculation. One really supposes that the crew saw a fire truck sitting on the runway with lights in motion, elected to initiate the takeoff, and then continued it until impact?
the fire vehicle entered the runway without notice or authorization, under speed, running lights, enroute and responding to another aircraft on the other side of the runway. The incursion occurred at the intersection of Bravo and Rwy16, approximately 4,000' into the takeoff roll. The amount of time that existed between recognition of the firetruck's incursion, and the impact, is unclear, as is the action taken by the crew in response. What is clear is that impact occurred, and a subsequent fire happened.
Wild speculation on the decision making or actions of the crew is unwarranted, and unprofessional. An investigation will play out, and information will become available, when appropriate, associated with that investigation and any results or conclusions thereof.
