If you got stuck while moving at around 1000 MPH you have bigger problems.

And if you survived the crash - how would you get out? The capsule is unpowered, and they don't make cables long and strong enough to pull you out.

But assuming rescue was possible, I suppose they could drop small emergency coolant refill bags down to you.

Then you just poor a ton of liquid nitrogen down afterwards and cryonics will take care of the rest (give or take 50 years).
