Space debris from rocket bodies orbiting Earth could pose an increased threat of striking aircraft as it falls from space, according to new research.

Uncontrolled space debris reentries are of growing concern. The prospect of leftovers from space hotfooting into the Earth's atmosphere can create a collision risk with aircraft in flight. While the probability of a strike is low, the consequences could be catastrophic.

As more space junk is falling to Earth uncontrolled, scientists are using seismometers to track the debris.
