Imagine an airplane crashes under mysterious circumstances. Except in this world, there is no government oversight, and all investigations are done voluntarily by the airlines themselves. Nonetheless, the airline wants to reassure their customers, so they do an investigation. To investigate, the airline invites three of the world's most respected airplane researchers to look into it. Except by the time the researchers get there, the airplane has already been disassembled and melted down into little cubes. The researchers are instead given the logs of all the airplane directions and the transcripts of the conversations between the pilot and the copilot. Except one tenth of the log has been deleted. And the airline also tells the investigators that they can only look at the time between when the airplane first started losing altitude and when the airplane made contact with the ground and that all investigation of the time before the airplane started losing altitude is off limits. Also there are a lot of rumors in the airplane community of a few other airplane crashes under somewhat similar circumstances, but the airline says that these are also explicitly off limits. When the researchers arrive to review the logs, they find that the logs are 10,000 pages. But they only get six days to read them, and half the logs don't arrive until day 4. Now you understand the independent METR investigation.
