    Air India 787 crashes on take off

    It would be interesting to know which switch was moved first. I guess the next phase of the investigation will delve into the crews lifes, medical, financial situation. Maybe one of them has a flight simulator in their house that they practiced this on.

    Air India 787 crashes on take off

    Apparently most of the circuit breakers in the 787 are virtual, it doesnt seem like any real breakers exist on the flight deck any more.

    New Orleans anti-vehicle measures

    What im curious about is that if barriers need to be designed differently for EVs, as they tend to be much heavery, have more torque, and different weak spots. The truck used in the new Orleans attack was a F-150 lightning all electric vehicle (welcome to the age of sustainable terrorism).

    New Orleans anti-vehicle measures

    as long as the pins that hold the wheels in place have been removed the barrier should work as intended.

    PW1500G engine failure A220 swiss

    HFC-125 appears to be the replacment for halon 1301, its decomposition products are still pretty nasty (hydrogen fluoride). Those halon systems tend to hang around until they are discharged.
