Factual error: Dr. Fielding is dead inside the JPL building. His blood is dripping onto a telegraph key and it is sending perfectly comprehensive Morse Code. The blood drips are too random to do that. (01:13:25)
Suggested correction: It's clear he was alive at one point, and the way he has positioned shows he was probably already sending that. There was a break from him sending it, and it's clear the kids didn't understand the morse code, which could be the point his blood was dripping.
That could be. OK.
