    Less than 3 hrs ago a Delta regional jet crashed at Toronto airport. All 80 on board survived but with 15 injuries including 3 critical.

    The landing was with crosswinds on a snowy runway. What we know for sure so far is that aircraft tipped past horizontal enough to 'dig in' right wingtip. It inverted, shearing off right wing and vertical stabilizer (tail).

    CRJ 9 has rear engines, and that is a good thing in wing-loss. There was engine/fuel fire, but all exited. It take a lot of energy to detach a wing; some if that would have been felt by seated occupants before rolling over. Terrible experience, then 2 cabin crew needed to get 76 unbelted and out the door. Quickly.

    This will be thoroughly investigated as always. Crosswind was within stated limits, but it will be interesting to see if crosswind landings on to slick runways ought to have lower limits. The main gear needs to 'bite' very well in crosswind landings because there are large lateral forces.

    I saw an in-cabin video which clearly showed one of the flight attendants doing exactly what she was supposed to, and several passengers standing on the ground outside the aft right overwing exit assisting the camera operator and others with evacuation.

    Several flight attendants in the family already commented on it; good work was done in the worst of situations.

    Extremely windy day regionally- even where I am near Philadelphia we saw numerous widespread power and telecom outages, many more missed approaches to all the airports.

    This was just the worst one.

    My experience as a general aviation pilot is very limited, but I know about and have done crosswind landings. One flies precisely towards runway centerline with airplane (miss) angled into the crosswind. Just before runway contact, straighten out which net effect makes the upwind wingtip low. Then ride 'er in.

    Crosswinds will vary during those last few interesting seconds and aircraft vary in responses. As pax in commercial, my most interesting landing was at Ontario suburb of Los Angeles. I could feel though my seat (good person) that pilot was doing many professional things rapidly.

    Again, a baby pilot is writing this. If runway is cross windy, is snow covered and I can't see runway centerline, I would divert as far as fuel onboard allowed to find a place I could manage to land.

    Pro pilots are much better. Whoever landed in Toronto before this mishap did fine. We may see tighter limits on crosswind + snow landings imposed in future.

    Kudos to those who survived. Just remember, hindsight is always better than foresight.

    I former private pilot, +300 hours, my most challenging crosswind was at First Flight Airport at Kitty Hawk. Keep the speed nailed and land on the upwind wheel. Smoothly without wasting time, get the other wheels on the ground and dump the flaps. Rudder to nose wheel steer and main gear toe (individual) brakes as appropriate. At the time, blowing sand had patterns like the snow and ice in Toronto. Taxi to end to turn around and taxi back on the runway.

    My Cherokee 140 weighted a fraction of the Toronto jet and I could not fly faster (except in an unsafe dive,) 124 knots. That jet would land at 135 knots.

    There will be lesson's re-taught after this and every other accident. The Federal Aviation Rules are written in blood.

    ps. Found this online:

    . . . firing hundreds of employees at the Federal Aviation Administration (FAA), including some who maintain critical air traffic control infrastructure, despite four deadly crashes since inauguration day.

    According to the Professional Aviation Safety Specialists (Pass) union, “several hundred” workers received termination notices on Friday.

    Many of the workers were probationary employees, those employed for less than a year and lacking job protections, which makes them low-hanging fruit . . .

    . . .

    The firings at the FAA do not include air traffic controllers, but did appear to include engineers and technicians.

    ^ That.
    All of my stick and rudder time is from the right seat, and I wear dolphins - not wings.....aaaaaand these are early hours.
    It WOULD appear that the flight crew earned their bucks.

    NBC pundit blames Trump for Toronto Delta plane crash... even though it happened in Canada | Daily Mail Online


    *sigh!*
    FAA has 45,000 employees.
    Less than 400 probationary employees , hired less than a year ago - were simply NOT HIRED.
    That's DIFFERENT than being 'fired' WHICH IS WHY they call it 'fake news.'

    Those that will be 'fired' in the future will probably include some people approaching their '30 year pin' who will be offered a paid, early retirement - or?????
    Perhaps????

    Like the military they will be REQUIRED to do more with LESS.

    My last employed year, I was admin for the NASA subcontractor, my employer, operated, SNMP network servers. We knew the software would go 'End of Life' so three younger folks were hired; a source selection for the next monitor, and; I made sure I knew nothing about the new system.

    At age 64-66, my employment would come to a close either voluntarily or otherwise. Regardless, my home bound wife needed more of my time in her last years. So when the software went, "End of Life," I supported server shutdown and left a few weeks later.

    It would have been a dam shame if the youngsters had been laid off before me.

    There are (by some estimates) 2.3 MILLION employees in government.
    Do we need them all?

    What's the BEST (most equitable?) way to start cutting back???
    What's the right number?

    I will cast my eye inward FIRST.

    USN:
    We have 14 'Boomers.'
    No.
    Not people over 65......Strategic Missile Subs (SSBNs.)
    The math probably goes something like 5 out now, 5 getting ready to go out, 2 in intermediate overhaul, and two in or about to go into extended overhaul.
    The sea is not kind to ships nor their crews and 'boomers' have famously HIGH op-tempo or 'at sea' time.
    Ships are more expensive but the crew is WORTH more!!!
    OH....and the newest T-hull is.......checking......28 years old - which is about 60 years old in sub-years.
    The OLDEST boomer is over 40 - which is BIDEN years old in terms of submarine service!!!!!!
    I used to remind my shipmates when we were at 'test depth' that the boat was build by the lowest bidder! :)

    So....
    What does ALL THIS MEAN????

    -how many boomers do we really NEED???

    0?
    4?
    10?
    The same could be asked of USN Carrier Strike Groups.....destroyers.....
    USA Infantry divisions....
    ASAF squadrons....

    They're going to be asking US to pay for the replacement for the USN Tridents - an unqualified SUCCESS in their task.
    (NOT ALL USN ships have this distinction!!!!!!!!!!!!!!!!!!!!!!)

    How many do WE buy to replace the original 16 (now 14?)
    The USN wants 12.
    A more reasonable current number is 10.

    Me?
    I would call for 6.
    2 out.
    2 ready.
    2 in overhaul.
    MAYBE 5 - if the REST of the US Government would be willing to settle for a 50% (really 75%!!!!) cut in their current funding.....

    Put your partisan hat away for one moment and apply that same math to:
    The rest of the DOD.....
    The rest of dot.gov.....

    YOU are BOTH an engineer and a former government employee.

    Do the math!!!!!

    Years ago here in Prius Chat we had a thread, talked about loss of Malaysian MH370. As a result of that old thread, I eventually became a citizen "expert" on that situation. I am not a pilot, but became quite the B777 flight sim expert on MH370. But I cannot land the aircraft properly, all I do is crash landings in the ocean. New search to begin this week, but I have become quite negative that the powers-that-be, due to denial, do not want to search where. aircraft actually flew. People are reluctant to admit it was a nefarious flight so the focus is ghost flight, or what I call the sanitized hybrid case, intentional ghost light.

    Re; Toronto, quite a few YouTubes on windy "crab style" landings, I guess this one lost the aircraft, happy for PAX. I am just a few miles from DCA where we had the mid0air collision. Fort Belvoir fairly close, where the copter was from. My neighbor worked there in night vision dept, but retired a few years ago. I used to get over there once a year for an activity. Locally we lost some ice skating students, parent, and coach.

    Couldn't get past all the TMZ ads.

    I'll wait for the Youtube vids

    That does look like a substantial sink rate, and the first flame flashes almost appear to be from both engines at the same time- as if they'd independently ingested broken chunks from the landing gear/wing roots on their respective sides of the fuselage.

    Eyeball/stopwatch suggests 1200fpm sink rate; pro pilots tend to frown on anything over 240.

    Bad angle for the yaw rate....but I've seen worse.
    As I've already admitted...all of MY stick and rudder time was from the right seat or an armchair.
    I'm pretty sure that since Oh Canada!! hasn't fired all of their transportation and aviation employees in the last 4 weeks we'll know more in the next few weeks.
    Did the aircraft break?
    What were the winds?
    Does Oh CANADA have ASOS and LLWAS?
    TORT limits????

    Soon we will know 'all the things....'
    Thank GOD above that no souls were lost if the reporting is accurate.....

    Taken from the cockpit of another plane. The roll is not related to the wind, the wind is blowing snow parallel to the landing course.

    The rear landing gear is not visible in the video and many photos.

    But if the plane flips 180 degrees, the landing gear should be intact.

    The decoding of the black boxes will explain the reason.

    As bad as it looks this worked out very well. CRJs do not have good survivability statistics.

    The wings detaching helped a lot. The fuel tanks are in the wings so the risk of explosive fire was greatly reduced.
