I know at my old plant we'd get all sorts of OE from the airline industry and YES they're SCARY!
Mike, if you thought the OE from the airline industry was scary, you would be frightened silly by the people we hired from an unnamed major airline that has Detroit and Minneapolis as hubs, and was just bought by another major airline that uses a Greek letter for its name.
Luckily, we were able to send one of them to the nuclear waste dumping ground that fossil generation has become, but the other one is still hanging on, still acting as a precursor to a major incident.
