Why does smoke come out of planes?

The reason airplanes leave a white smoke trail in their wake is because their exhaust gases contain moisture that condenses at high altitudes. As the airplane’s engines release exhaust gases, moisture vapor is released as well. Rather, they are simply the result of moisture vapor in an airplane’s exhaust gases.

What is the exhaust at the back of a plane?

You may have noticed a strange phenomenon when looking at the rear of aircraft parked at the gate: they’re venting out exhaust from a little hole in the tail. Through that hole is the Auxiliary Power Unit — the little engine that could. As with everything in aviation, it’s primarily known by its acronym, the APU.

How do toxic fumes seep into air on planes?

The air you breathe on airplanes comes directly from the jet engines. Known as bleed air, it is safe, unless there is a mechanical issue — a faulty seal, for instance. When that happens, heated jet engine oil can leak into the air supply, potentially releasing toxic gases into the plane. Passengers struggle to breathe.

What happens if you get sucked into an airplane engine?

Yes, you can easily get sucked into an operating engine and it can be fatal. When an engine operates, the amount of air getting sucked though its intake can cause a low air pressure area in the surrounding areas and pull you towards it.
