From what I've read, one of the things the helicopter project did was to see how well ignoring the usual heavy verification would go--it used consumer-grade off-the-shelf hardware as well, for instance.

Could you recall any sources to this?

Just because they are using OTS hardware doesn't mean it doesn't go through verification and testing, it just means they are buying hardware instead of making it themselves.

There's this recent-ish news article:

They have 2 sets of RAM and a RAD hardened FPGA that checks for bitfips in the memory. It can restart one that quickly that it can do it mid-flight. It's amazing what possibilities this could open up as doing intensive image processing on RAD hardened is expensive, or not even possible as it lags behind the state of the art.
