Why do planes break apart so easily when they crash?

Now as mentioned the engines are meant to detach easily. Wings also are not held on by more than a few bolts. Since they contain the fuel, if there is enough force to detach them, it's a good thing. read more

They do and they don’t. Compare the crash results over similar speeds of cars, buses, trains, planes. And especially notice the death and injury differences. A car crash in a mall parking loss is usually more serious than most plane crashes on landing. Partly the frameworks should collapse to absorb energy. read more

They just break apart and throw debris everywhere. The way a jet engine works is by taking in air via a turbine, compressing it, adding fuel, and igniting the fuel and high pressure air mixture to form a very powerful"jet". So when a plane hits the ground, assuming that it is still burning fuel, the engine is destroyed and the mist of fuel is ignited causing a deflagration. read more

And planes do break down now too, even those that pass the pre-flight checks. Which is why the planes are extensively monitored, so in case of trouble, they can, if possible, glide down to the nearest airfield. read more
