    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).

    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.

    Alaska Airlines flight forced to make an emergency landing...

    It's a brand of dish soap. I've used it to help fit crane tires, pump shaft seals, and as a cable lube. I would be surprised if Boeings SOP specifies dish soap.

    I-195 Bridge Closure, R.I.

    There is a rather unfortunate practice in some government agencies that when a consultant tells you his report is going to bare bad news, you tell the consultant to submit a draft copy (and never ask for a final copy) This is done because many FOIA laws exempt drafts. I worked for a state...
