Bfr 3.0


A little more gamma reveals the blended wing body replaced by much simpler beveled wings & canards. The wings & rudder serve as landing gear. Horizontal surfaces are folding, so they can be flat to provide lift, then be a triangle to serve as landing gear. The folding might also provide aileron functionality. There are a lot more windows & they're tinted. The single piece window of BFR 1 returns. The heat shield is a simpler flat shape.

The engines seem to be the scaled down raptors that were tested 1st, but with vacuum nozzles. He decided to reuse the test engine for the upper stage, while reserving the full size engine for the lower stage. It would speed up development to not delay the ship for the full size engine. A bit disturbing to see ablative nozzles.

A bit puzzling how vacuum nozzles would allow landings on 2 different planets with different air pressures. An overexpanded nozzle is too unstable.

They could also be full sized engines with retracting nozzle extensions.
