"Stoner rock band" sounds like something out of the Flintstones. :claireface:
Kugai:
Got the time for the Surgery on Monday. Gotta be there by 07:00 on Monday morning for early Surgery. According to the Nurse and the Doc, I should only be in till Tuesday - probably afternoon coming home - or Wednesday at the latest.
Got the Transport arranged, so I will have no troubles getting in.
Perfectly Reasonable:

Less than you think... depending on angle, by 5000 metres altitude it's slowed considerably, so impact velocity is about the same as if dropped from 5000m.
Depending on density and cross-section, that kind of shape might only hit at less than 60 km/h. If Jeph hasn't done research on it, he's guessed really well. Peak g-force might be 40g or so - 400 m/s-2.
The Genesis craft hit at 300 km/h, with a mass of 275kg and diameter of 1,5m, max decel 30g. Assuming 15 kg mass, 1m diameter, 50 km/h is about right. Might be less. A 90kg mass with that cross-section hits at about 200 km/h.

Isn't there an XKCD "What If?" about this?
Jynto:
There is. And spoiler alert: it wouldn't work.

Way to not make a fair comparison; you're taking an article based around a naked steak being dropped uncontrolled and extrapolating to a pizza in its own little oven/aeroshell combo.
Like I said, the hard part is letting through enough heat to cook it but not enough to destroy it and most of that would be because of the ridiculous variety of potential routes the thing has to take; anything from straight down twenty miles to a nice long 3000km cruise depending on the relative positions of Station and the Byooo-box.
Well, OK, second hardest part, after "get funding for orbital pizza delivery project (est $3bn)”
