Dark vegetation can hide sections of the fuselage.
Aerial searches are therefore not as simple as flying over an area and looking for a large airplane.
## The Ocean Is Even More Difficult
If an aircraft disappears over the ocean, the challenge becomes dramatically greater.
Investigators have to consider the aircraft’s final known position, wind, currents, altitude and speed.
Once an aircraft enters the water, wreckage may scatter.
Some pieces float.
Others sink.
Large sections can separate from the fuselage.
Ocean currents may carry debris hundreds of kilometers away.
And the aircraft itself may settle on the seafloor, where darkness, pressure and sediment make searches extremely difficult.
Modern underwater technology has improved the chances of finding wreckage, but even today, locating an aircraft in a vast ocean remains an enormous task.
This is why some of the world’s most famous aviation mysteries have remained unsolved for decades.
