Do you know how plane engines are tested? Well, this is how airplane engines are tested and why it is so important that every engine is engineered in a way to pass all of these tests, like the chicken, bird, and ever water test. Since a malfunctioning jet turbine will most likely end in a plane crash, manufacturers like making sure that the engines for new aircraft are made in a way that even when they fail does not cause any further damage to the flight.
