The Belgian Triangle Wave

From November 1989 through 1990, Belgium experienced one of the most thoroughly documented UFO waves in history. Thousands of witnesses reported massive triangular craft, and Belgian Air Force F-16s confirmed radar contact with objects performing impossible maneuvers.

The Beginning

November 29, 1989:

• Near Eupen, Belgium
• Two gendarmes (police)
• First official sighting
• Triangle with lights
• Wave began

The Witnesses

Over the wave:

• 13,500+ witnesses
• Police officers
• Military personnel
• Pilots
• Ordinary citizens

The Object

Witnesses described:

• Massive triangle
• Three bright lights
• One at each corner
• Often with red center light
• Silent or slight hum

The Size

Estimates:

• Football field sized
• Or larger
• Dwarfed aircraft
• Enormous scale
• Consistently reported

The Behavior

The triangles:

• Moved slowly
• Hovered
• Then rapid acceleration
• Silent operation
• No sonic boom

Eupen Sighting

The gendarmes:

• Heinrich Nicoll
• Hubert von Montigny
• Extended observation
• Professional witnesses
• Documented extensively

Police Reports

Throughout Belgium:

• Officers reported
• Multiple sightings
• Official documentation
• Pattern established
• Mass phenomenon

The Belgian Air Force

Military response:

• Took reports seriously
• Unlike other nations
• Investigated openly
• Released information
• Remarkable transparency

March 30, 1990

Key night:

• Multiple radar contacts
• Ground and airborne
• F-16s scrambled
• Chase began
• Historic intercept

F-16 Scramble

Two fighters:

• Launched from Beauvechain
• To intercept
• Radar locked targets
• Multiple times
• Then targets evaded

The Radar Data

F-16 radar showed:

• Targets performing
• 1,000+G maneuvers
• Dropping from 10,000 to 500 feet
• In seconds
• Impossible for aircraft

The G-Forces

Calculations showed:

• 40 G acceleration
• No human could survive
• No known aircraft capable
• Technology unknown
• Documented on radar

Colonel Wilfried De Brouwer

Belgian Air Force:

• Oversaw investigation
• Spoke publicly
• Released radar data
• Extraordinary openness
• Credible official

The Photo

Famous image:

• Triangle with lights
• Taken during wave
• Widely published
• Later disputed
• Remains controversial

SOBEPS Investigation

Belgian UFO group:

• Extensively documented
• Worked with military
• Collected testimonies
• Published report
• Thorough research

Skeptical Analysis

Some suggested:

• Military aircraft
• F-117 stealth
• Ultralight aircraft
• Mass hysteria
• None fully satisfying

Against Conventional

Problems with explanations:

• Size too large
• Behavior impossible
• Radar confirmation
• Military couldn’t identify
• Duration too long

The Wave Ends

By 1991:

• Sightings declined
• Wave completed
• Pattern typical
• Came and went
• Mystery remains

Official Position

Belgian Air Force:

• Could not identify
• Objects were real
• Not conventional aircraft
• No explanation
• Honest assessment

Significance

Belgian wave significant for:

• Mass witnesses
• Military involvement
• Radar confirmation
• Official transparency
• Physical evidence (radar)

Legacy

The Belgian triangle wave remains one of the most credible mass UFO events. Military radar data, thousands of witnesses, and unprecedented official openness make it a cornerstone case in UFO research.
