    The lower mainland is not equipped to handle snow. When I lived out there in the late 60s the city of Vancouver snow plow blades were raised by a second person in the cab with a hand operated hydraulic pump. Talked to my brother today who lives in Langley. In downtown Langley he seen a city employee with a 5 gallon pail and a coffee cup spreading salt on the side walks. Ice falling from Port Mann Bridge breaking windshields.

    I retired thinking that I had done enough but I find I miss it so I took on a project (part time) to document it all and perhaps make a book out of it; depending on what the sponsors will support!

    That's a book I'd enjoy reading!

    I’ll throw in my story. In 1968, I worked at Prudhoe Bay Alaska on the discovery exploration well. We were 5 miles from the BeaufortSea/Arctic Ocean. Back then any exploring had to be done in winter due to the permafrost. In January it got to and stayed at -69F for three days (nights). The sun never rose. It was an experience that I never want to go thru again. The only plus was the non stop northern lights. But we had to be outside to watch them.

    This is more than a bit off the topic of "-40C is damned cold" but is an interesting little diversion for me! I have never tired of airplanes since I first started seeing models fly on the Tantramar Marshes near Moncton, NB with my Dad when I was just a little boy and can still talk about them, tinker with them and play with them day and night. My work always seemed like play for grown-ups to me and I enjoyed the ride immensely. So many adventures!

    Sorry folks for (partially??) hijacking the thread.

    That would require a rather lengthy and involved explanation but it begins with the fact that aircraft flight test instrumentation systems were usually one-ofs. Despite assertions you may have read that electronics are immune to the cold, they are not and the only way to find out for sure is to get them really cold and do end to end testing to ensure that they are behaving as designed/intended to work. Other aspects of the instrumentation such as adhesives, wiring and plumbing can be temperature sensitive too. So the way we "qualified" each particular set-up was to cold soak it IE let it reach a very low ambient temperature then run a series of performance tests on it to try to find out if performance was degraded; adhesive bonds were broken, wiring had pulled loose from connectors and a myriad of other cold induced failures that seem a bit far-fetched unless they are part of your bread and butter core business.

    Does that help? I sometimes forget that the argot of the flight test world is not familiar to everyone and drop into it too readily. Sorry about that.

    Oh, no apologies needed, thats really quite interesting. I think I was most thrown off by the phrase "cold soak" , which I interpreted literally and pictured you hosing down airplanes with water in -50! What planes did you work on?

    Checked the temperature this morning my thermometer said -5 but it is actually closer to -40 again.
    I think it’s broke, frozen, gave up the ghost.

    CFB Wainwright in the early '80s, me and a sergeant were out in the middle of nowhere, -50 and a howling wind. The diesel in our armoured personnel carrier turned to jelly and the batteries crapped out. We stayed with the vehicle but that thing became a 13-ton magnesium icebox until we got towed out the next afternoon. The infantry had good winter clothing back then, and if I recall correctly we may also have had a bottle of issue rum. Good times.

    Ya, that's cold.

    I once went to Rochester Minnesota and when we landed it was -40 the next day it was 32.

    It's Alberta in the winter.
    That's what you expect.
    I, on the other hand have to deal with 4, humid, and cloudy, and am not liking it.

    Yup I’ve been here a long time and we expect winter.
    But -40 is getting harder to take as I age.

    I hear you Richard! I moved to Cold Lake with a mercury thermometer that went down to -40C/F and found out that wasn't sufficient range to be safe. I bought a bimetallic one that went to -50C and found out that didn't always quite cut it either; close but no cigar. The one in my car would hang with you to -60C (-75F approx.) and I never saw it colder than -52C at ground level in Cold Lake. That God Awful cold could be convenient sometimes in the flight test business because we could cold-soak aircraft instrumentation systems right on the apron by the hangars and correct snags/wring them out without burning up time and fuel flying!! Otherwise; I can see no upside to it!

    -40C/F is a pretty sporty temperature for those in the crowd who have no experience with such things; it hurts to be out in that. Concur with Richard's comment above: "Dry cold my A__!
