Especially considering the use of off-the-shelf Snapdragon 801.

There's some nice discussion about Ingenuity here: https://news.ycombinator.com/item?id=26177619

...This processor will have not flips on Mars, possibly up to every few minutes. Their solution is to hold two copies of memory and double check operations as much as possible, and if any difference is detected they simply reboot. Ingenuity will start to fall out of the sky, but it can go through a full reboot and come back online in a few hundred milliseconds to continue flying.

Reboot mid flight is a funny solution

Imagine telling an airline pilot to just reboot the whole plane if something goes wrong.

You'd be surprised. We only do that on the ground, though.
