OK, so let's say he drove 400 miles to get to the base (I admit it's not clear). Still, the NASA people didn't know where he lived? They weren't looking for him? He's their last hope and…they are surprised when he shows up? That's not a plot-hole?

Which 80%, if I may be so bold?

I list about 20 of them in a separate post.

I think the physics of that is solid—not much difference between a rocket and the spout of the extinguisher, it's just a matter of scale.

It's not the Republicans who have gutted NASA funding, is it?

If one were to compile a list of the plot-holes/unbelievable happenings in this film it would be quite lengthy. Like:
(SPOILERS)
1. I'm supposed to believe that Cooper lives a short pick-up truck ride from a secret NASA facility?
2. NASA is in desperate need of a pilot, yet they have no idea former NASA pilot Cooper…

EXACTLY. I could not get into Interstellar because the plot-holes were so huge, not because of some physic-geek quarrel about the relationship between gravity and time.

Or this: how does the bed guy know when to stop choking him out so he is unconscious, but not likely to die? Strangling a guy within an inch of his life and then taking a nap a foot away from him seems like an unwise thing to do during a zombie apocalypse.

Would've been even cooler if Rick had finished that guy off from under the bed, then slipped out of the room just as he 'turned'.

Because the plot demanded that the truck not be serviceable so Glenn would be able to get everyone to go back and hunt for his immortal lovey-dovey. So we get a nerd with a mullet who is supposed to be 'smart,' acting like the biggest shit-for-brains on the planet.

If a woman paints a picture of herself as a zombie, and it's indeed a self-portrait, doesn't that mean she IS a zombie?

Keeping one's legs hair-free in the zombie apocalypse only requires duct tape and courage.

Mass start biathlon is just simply awesome, easily my favorite sport of this games, and the only one that had me screaming at the TV. And it's a sport in which the US has ZERO medals, so you're not distracted by any kind of potential for American success.

The over 50 demographic may apply to figure skating—which mainly appeals to women, not men—but not to the X-Games sports, which appeals to those under 30 the most. For men over 40, there's biathlon and alpine skiing and the sliding sports, but that's about it.
