The
Mexican Air Force has released footage of what a UFO expert said were 11
invisible unidentified flying objects picked up by an infrared
camera as they whizzed around a surveillance
plane.

A long-time believer in flying saucers,
journalist Jaime Maussan told a news conference on May 11 the objects
were real and seemed "intelligent" after they at one point
changed direction and surrounded the plane chasing them.

"They were invisible to the eye but they were there, there is no
doubt about it. They had mass, they had energy and they were moving
about," he said, after showing a 15-minute video he said the
Defense Ministry gave him permission to publicize.

The ministry confirmed to Reuters it had provided the video, filmed
by the Air Force on March 5 over the eastern coastal state of Campeche.

"We are not alone! This is so weird,"
one of the pilots can be heard yelling, after the plane's crew switched
on an infrared camera to track the objects, first picked up by radar.

The film, recorded by a plane looking for drugs trafficking
near the Gulf of Mexico, shows 11 objects as blobs of light that hover
in formation or dart about, sometimes
disappearing into cloud.

Mexico's most popular nightly news broadcast showed the video on the
night of May 10.

Interviewed by Mausson on another section of the video, the pilots
said they grew nervous when the objects, still invisible, turned back
during a chase and surrounded the plane.

"There was a moment when ... the screens showed they were behind
us, to the left and in front of us. It was at that point that I felt a
bit tense," said Maj. Magdaleno Castanon.

Mexico has a long history of fanciful UFO sightings, most of which
are dismissed by scientists as space debris, missiles, weather balloons,
natural weather phenomena or hoaxes.
