This thread is an interesting read.
That gif in the OP is quite dramatic. I think the ships we currently have would be able to handle an atmospheric reentry relatively well :
- The amount of fuel we carry on board allows us to actively slow the ship down, while current reentry technology usually relies on friction and trajectory management to slow the ship. We have so much delta-V on tap, we can probably burn retrograde (or use the retro thrusters) for hours without running out.
- Our ships are able to approach quite close to stars, and sustain the heat for a few seconds even when approaching too close, thanks to our active radiators. Currently shields don't do anything for that, the hull materials and the radiators do everything.
So reentry temperatures of 3000 Kelvins for an Earth-like should be manageable, especially with the help of our thrusters, minimizing the amount of time enduring that level of heat.
- In atmosphere flight would also be fine, since we can already fly around planets with several Gs of gravity just fine. The presence of air would probably make the ships more sluggish, but nothing major.
For these reasons, I think the glide and approach mechanic currently ingame would work fine. I like the idea of having to follow an ideal trajectory, or maintaining a specific angle of attack to avoid overheating.
edit : due to real life events, it took me ~ 45min to post this, so everything is ninja'd multiple times
Pretty much all there is to it ^ Hopefully FD will add some drama to it for gameplay reasons, although completely unnecessary considering the capabilities of our ships.
