    @Rory do you know anything about the source of their capital? Govt half-sponsored, external investor or maybe the glider pilot used his pocket money earned flying glider charter?

    The story of unmanned tug sounds for me immediately like total bs for noobs. One of tug pilot's jobs is intelligent scenario management when tug loses some power and both are low. There are no black&white options at this stage and workload requires some 2.5 human pilots full time, terrain avoidance and landing site selection being most important pilot skill in this case. I would imagine unmanned glider with human tug as intermediate case in any way, certainly not the opposite.

    @Fabien

    Lightbulb for status? Cmoon. How important said status should be for such a bulb, DEFCON? Tilt sensor is the right answer.

    @Gary relax, it cannot be that old. As I remember those were the days when GPS was already coal-powered, wooden solar cells were already a thing of the past and a subject of many jokes among those in the know.

    Like MarcS said, It's an electrolytic tilt sensor.

    I think I´ve seen some of these bulbs before, years ago in controller boards for model submarines. I think these are half fluid filled with sensor wires for tilt sensing. In an autopilot they could be used for gravity vector sensing...

    That was the time before cheap MEMS..

    Bur i do like Melihs idea!

    My guess it is a heatsource to keep the other stuff at a consistent temperature.

    It is a mercury switch for orientation sensing ;)
    It is detecting up side down

    no it's a Tube! way better sound quality than transistors!  and it was pulsing too... I guess it's the first iteration of the led Show code.
