The sensor failure caused the plane to decide that a human would be better flying, but the stall warning was still working. If the pilot had put the nose down, and increased engine speed the plane would have flown out of the stall. Unfortunately the pilot didn't know the plane was operating in "reduced" mode and thought the stall warning was malfunctioning, raising the nose and deepening the stall. The stall remained recoverable until quite late into the incident, if the pilot had taken the right actions.

Actually it's even better than close, the previous figure had an error of 120 million years either way. So, this new figure while being at the outside of that range is still within it. I haven't seen any error bounds on the new figure, but assuming it's fairly small this observation ties in exactly with what was previously observed.

My solver finds all solutions to a given puzzle, when given a choice it recurses through all possible branches and returns all valid solutions. For this puzzle it returns only one.

Your second solution isn't a solution to the given puzzle, D2 should be 5. (Where A1 is the bottom left)

Your first solution is incorrect, B6 is 5, not 3. (Where A1 is the bottom left corner)

Could you provide the other solutions you've found, my solver only finds one valid solution. If it's going wrong I'd like to debug it.

Care to give more than one solution to this sudoku? I can only find one with my solver.

It also has an analogue TV out.

The $25 version will have 128Mb, and there's a $35 with 256Mb.

It will run Linux, originally the hope was to run Ubuntu but with their restricted memory footprint they're having to go with a version of Debian instead. Amazing what you can learn when you watch the full video and actually listen to it.
