That first picture is of the initial abort, you can see the speed brake out. If I remember correctily there is a “ground auto” for the speed brake on the SBR75. If the power is reduced to idel and the squat switches think they’re on the ground the speed brake deploys.
The SBR65 had it also (if the speed brake wasn’t disabled) and also a ground auto for the spoilers. I can’t say for sure if the 75 had ground auto spoilers.
Amazing pictures though.
THIS POST discusses losing a tire on a Sabreliner during takeoff.
Going to Cartagena, sounds similiar to the G-II that crashed in mexico a few weeks back. an American plane, on a lease, traveling around the Central America area. Obviously the accident has no similarity but the usage might be an interesting parallel, we will never know.
