Your question was based on fundamentally flawed premises, and they didn't wanna bother to explain why the premises were flawed.

I can understand that, watching forums where questions based on zero knowledge of the subject of the forum are asked every day is frustrating. But even a rudely worded "The speeds involved are completely different, look up reentry heating. And terminal velocity isn't a set number." Would have been a million times better than what they did.

But that sounds "unprofessional" or whatever bullshit, and they want to sound official and proper at all times. Only insecure losers that care about that kinda stuff become reddit mods.
