Default Re: Technology related anachronisms on TV and in films etc.

A few evenings ago there was an aircraft crash investigation programme which was very interesting. On take off a warning lamp had appeared and take off was aborted, on investigation the engineers cleared it to go as it was just a faulty wing surface temperature sensor. On the next take off the plane crashed as it couldn't get enough lift because the flaps weren't down although they were set to be.

The reason was found to be a relay failure, the one that fed the temperature sensor also fed the flap circuit.

The real point of the post though is that while they were fault finding, every now and again they flashed a circuit diagram on the screen and it had valves in it, unless I am mistaken they don't do that any more.
