True story! The landing was fantastic, no doubt, but this footage is a thing of pure beauty: https://www.youtube.com/watch?v=EzQpkQ1etdA&feature=youtu.be...

I enjoyed watching Blue Origin's landing as well (https://youtu.be/9pillaOxGCo) and from their video it looks like engine restart is at five thousand feet with full burn at one thousand. Do we have similar numbers for Space X?

I am curious what threshold differences there are between teams, both are doing amazing work.

btw, this portion of the return where they did the entry level was most impressive for space x (https://www.youtube.com/watch?v=EzQpkQ1etdA&t=1145s)

SpaceX rockets have to shed a lot more velocity the numbers are not comparable.

At around T+8 minutes it's really obvious how the rocket is actually gliding at an angle as it comes down, to steer itself towards the landing site. A cylinder might not make a great glider, but it has significant lift especially at these velocities.
