    The one that went into the Hudson hit so many birds they stalled out both engines. A large bird hit a B1 bomber and brought it down. A plane going at 200+ mph suffers a lot of damage no matter what it hits.

    Bird-strikes really are the greatest risk to modern airliners.

    That crash -- Ethiopian Airlines -- is the combination of several factors.

    1- a bird hit one of the angle of attack sensor, which then started reading wrong

    2- the aircraft does not have the optional "AOA disagree" warning--it was even suggested that the AOA disagree warning was not even functional

    3- the 737-MAX has a system called MCAS that is supposed to make the plane 'feel' like the 737-800, despite having more powerful, heavier and differently placed engines. And to prevent the plane from stalling, that system relies on a single AOA sensor, which happens to be the one hit by the bird.

    4- because the system was meant to be transparent, pilots were not trained and perhaps not even told about it being there.

    So there you have it: a poorly designed system, lacking redundancy, getting compromised data from a defective sensor without the crew having have the training, and perhaps even the knowledge of what that thing was doing.

    If an aircraft loses its engine(s) in flight it can not park on a cloud and wait for maintenance to reach them.

    No power, no flight.

    The plane that lost both engines in New York and landed in the Hudson river was an Airbus A320, not a Boeing 737, but that's beside the point because an incident like that could have happened to any commercial airliner.

    How does it happen?

    Well, you have to understand how a modern high-bypass turbofan engine works. It has a core in the center that uses a turbine to spin the entire engine, the center of the engine has multiple compressors that compress air as it comes in, and blows it out the back of the engine at high speeds. But most of the air that goes through the engine bypasses the center compressors and is blown through the engine by the large fan blades. (thus the reason its called a "high bypass turbofan" These engines are used on modern jets because they're the most fuel-efficient design available.

    The fan blades are strong enough to withstand the impact of most small birds. Small sparrows and pigeons just get shredded and blown out the back without causing harm to anything except the bird. But Canadian geese can weigh 15lbs or more. If one of these is sucked into the engine at high speed it can crack the fan blades. Once the blades are cracked they are spinning so fast that centrifugal force will cause them to come completely apart.

    Once you have a few broken blades the center of gravity of the engine will be off-center. This imbalance will cause the engine to vibrate so hard that it could damage other components or completely destroy the engine if the bird strike didn't already render it useless.

    Normally if this happens to ONE engine the pilot would declare an emergency, shut down the damaged engine and fly back to the airport using the remaining good engine.

    The Hudson river miracle was the extremely rare case where the plane flew right through the middle of a flock of birds so that both engines were damaged beyond function. It also occurred at a very low altitude which gave them very little time. Had this happened at higher altitude they might have had enough time to glide back to an airport. But then again birds don't usually fly that high.

      You’re a few days behind the times. It was revealed that it was a birdstrike that disabled the AoA vane that caused the Ethiopian 737 to crash.

    A Canada Goose can weigh 15 pounds. Hit one at 200 miles an hour and it's like being hit by a bowling ball at that speed.

    Break a turbine blade or two in both engines and it is lights-out.
