Believe it or not both experimental and production ready equipment has malfunctions and failures all the time and most of the time it has nothing to do with Linux:
What went wrong with the Hubble Space Telescope
“It’s difficult to overstate what a disaster this was and the humiliation faced by NASA; not just as an organisation but also the individuals who worked for the agency. A good friend of Pellerin who worked on the telescope fell ill in the wake of the launch and died. Two of Pellerin’s senior staffers had to be removed from their offices by guards and taken to alcohol rehab facilities. “These are PhDs sitting at their desk getting drunk; this is how bad the stress was,” says Pellerin…”
"“He says, ‘What do you know about spherical aberration?’ I said all I know is that when amateurs build mirrors and do it sloppily they get what’s called a downturned edge, and on different radii of the mirror it focuses the light on different parts of the optical axis and it’s physically impossible to ever focus a telescope; they’re useless.”
Pellerin’s boss responded: “Well you launched Hubble Space Telescope with a spherically aberrated mirror…”"
““In 1986 I drove into my parking place at NASA headquarters and my staff members are waiting for me there and it’s very unusual,” Pellerin says. “They ran up to me and said, 'Charlie, Charlie, Challenger exploded…””
"Pellerin watched the Challenger failure review closely. “I had good friends who I thought were good solid engineering managers who worked on the boosters so I’m trying to figure out what happened,” he says.
“I saw this guy, Richard Feynman, who was a review board member, take a piece of rubber O-ring and put it in his icy water on television, and showed that it stiffened up. So immediately I said, ‘Oh, that’s the technical problem, they didn’t do the O-ring well.’”"
