I (briefly) worked as a test engineer on a similar kind of contract. To meet the UX requirements for the system we were building, it had to be reliably operable in sea state 7+. The customer wanted touch screen interfaces. I exited that project when they were looking for volunteers to go spend time offshore in the Gulf of Alaska in bad weather, because that was the test environment they could find that met the requirements. Insanity.

I forget who said it, but there's a quote about how _of course_ we know more about space than the bottom of the ocean - in space we only have to deal with one atmosphere.

I found that sea, space and automotive are the three most hostile environments, each with very different requirements that made it hard in different ways.
