But a new U.S. government report fails to give a definitive explanation of UFOs spotted by military pilots.

It finds no evidence they are linked to aliens — but doesn't deny the possibility either.

Two people briefed on the report say it does not rule out that what pilots have seen may be new technologies developed by other countries.
