> It was also pushes the boundaries of what aircraft were capable of Are capable of. The SR-71 remains a marvel and it's unlikely that we could build something better today with the same design constraints. Which is part of why the successors to the SR-71 removed the on-board pilot (UAV) or the ability to lift-off without aid (satellites).
