Jet2’s Mysterious Flight Code ‘VX99’ Leaked—What Are They Really Hiding in the Skies?
The commercial aviation industry is no stranger to cryptic designations and hidden protocols, but when a seemingly innocuous Jet2 flight was flagged by an anonymous whistleblower for operating under the mysterious code ‘VX99’, speculation exploded across aviation forums, conspiracy blogs, and eventually mainstream media. Was this merely an internal routing code, or did Jet2’s secret flight have something far more enigmatic — and potentially sinister — concealed at 35,000 feet?
The Whisper That Started It All
The story began in late March 2025, when a former Jet2 operations analyst, using the pseudonym “Airlock_97”, uploaded a redacted logbook entry to a private aviation Discord server. The log, barely legible through heavy censorship, showed multiple anomalies: a Jet2 aircraft, departing from an undisclosed UK airstrip, listed under the unusual call sign ‘VX99’, operating without passengers, and filed under “Non-Civilian Routing Clearance.”
Within 24 hours, aviation enthusiasts across Europe were decoding the flight path using flight radar backlogs, satellite imagery, and old transponder logs. The community quickly noticed a pattern: VX99 flights had occurred five times since 2022 — all between 2 a.m. and 4 a.m., and all vanished from radar roughly 30 minutes after departure.
Jet2, when approached for comment by Aviation Today, simply replied: “VX99 is a training designation used internally. No further information is available.”
But the internet wasn’t buying it.
Strange Detours and Black Zones
What piqued investigators’ interest further were the disappearance zones — airspace sectors marked as “black zones” on military aviation maps. These regions, scattered across the North Sea and over the Scandinavian Arctic Circle, are typically reserved for encrypted government operations, intelligence drone corridors, or weather manipulation tests (according to some theorists). The idea of a low-cost airline even skimming these zones defied logic.
According to one self-proclaimed radar analyst, Marcus Hallam, who has a 14-year background in military aviation logistics: “There’s no reason for Jet2 to be in those areas unless they’re running something way beyond commercial operations. That flight code doesn’t exist in any civil aviation registry. I checked twice.”
Some began linking these flights with unexplained phenomena: erratic radio signals captured in Norwegian airspace, odd contrails observed above Aberdeen during full moon nights, and a chilling, now-viral video that showed a Jet2 aircraft — allegedly the VX99 — flying with no lights, just after 3 a.m., over the Yorkshire Dales.
A Jet That Doesn’t Exist?
Another bizarre twist came from aircraft spotters at Manchester Airport. A group of enthusiasts claimed to have seen a Jet2 Airbus A321 with no tail number or airline branding, moving unusually fast toward Runway 05L in the dead of night. One of them, 19-year-old Ryan Levesque, posted an image to Reddit that went viral: a blurry silhouette of a plane, its windows completely blacked out, and “VX99” scribbled on a service vehicle parked nearby.
Jet2 has no public aircraft with such livery, nor does its publicly disclosed fleet align with the details described in the sighting.
To add fuel to the fire, satellite images from a private Ukrainian imaging company allegedly showed a Jet2 aircraft parked at a remote airfield in northern Greenland — a place far off Jet2’s normal European circuit. The images were reportedly purchased by an anonymous deep-pocketed buyer before being pulled offline, raising even more eyebrows.
Disinformation or Hidden Mission?
Some experts suggest the VX99 flights could be nothing more than high-level simulations or contract-based operations for governments — possibly involving the UK’s Ministry of Defence. Jet2 might be running covert atmospheric monitoring flights, collecting meteorological data, or testing radio jamming technologies on behalf of a third party.
However, detractors are quick to counter: Why a budget airline? Why Jet2?
“Outsourcing covert ops to civilian entities is cost-effective and offers perfect cover,” explains Dr. Hannelore Dreschler, an aviation historian from the University of Vienna. “No one questions a discount airline. It’s camouflage in plain sight.”
Others go further, theorizing that VX99 is part of a larger NATO program — one that masks clandestine surveillance missions beneath the veil of ordinary commercial flights. The idea is not unprecedented. Historical declassified records reveal that Pan Am and Lufthansa were once involved in Cold War aerial eavesdropping.
Whistleblowers and Mysterious Disappearances
Three weeks after Airlock_97 dropped the first breadcrumbs, their Discord account went silent. A final message read only: “They knocked. VX99 is more than a flight. It’s a vault.”
Users who attempted to trace Airlock_97’s IP address found only dead ends — rerouted nodes through Malaysia and Slovakia, typical of someone skilled in digital obfuscation. Even more disturbing were rumors that two Jet2 employees — one flight dispatcher and one maintenance technician — were placed on “permanent leave” after being caught discussing VX99 via encrypted messaging apps.
No further records of those employees exist online. Their LinkedIn profiles were deleted, and one even had their address scrubbed from public UK databases.
The Cargo Theory
A leaked air traffic control memo obtained by FlightEye Journal pointed to a much darker interpretation: VX99 isn’t about people — it’s about cargo. The memo, classified under “Private-Legal Intersection Directive 7A,” indicated that an unregistered Jet2 flight had requested emergency clearance to land at RAF Lossiemouth due to “unstable payload.”
Unstable?
Some believe Jet2 might be involved in discreet biological sample transfers for pharmaceutical giants. A disgraced virologist, Dr. Peter Lomond, even claimed during a podcast that “live genomic experiments” are being transferred on night flights by unwitting carriers. When asked to clarify, he stated: “VX99 is the ghost truck of the skies. It carries what no land vehicle legally can.”
Jet2, once again, refused to comment.
The Spiritual Edge
Naturally, the mystery attracted attention from the esoteric community. One fringe theorist, known only as Velma9, compiled an entire 65-page dossier suggesting that VX99 is numerologically tied to “sky gates,” claiming that the flight opens celestial portals via electromagnetic resonances at high altitudes.
As absurd as it sounds, her TikTok videos gained over 4 million views. Comments ranged from ridicule to genuine concern, with some users claiming they experienced nosebleeds, disorientation, and “visions” after flying on certain early-morning Jet2 routes. No credible medical evidence supports these claims — but the phenomenon persists.
Parliamentary Whispers
In a rare move, Labour MP Diane Redcroft called for a formal review of “Jet2’s compliance with standard civil aviation transparency requirements” during a session in the House of Commons. Though laughed off by some MPs, Redcroft insisted that she had received multiple anonymous letters urging her to investigate. “I don’t claim to understand what VX99 is,” she stated, “but when an airline begins operating flights that vanish midair and officials pretend it’s routine, we owe it to the public to ask why.”
The Civil Aviation Authority has yet to respond publicly.
Jet2’s Silence
As of today, Jet2 has issued only a single additional statement regarding the controversy: “Jet2.com operates in full accordance with the UK Civil Aviation Authority and follows all international safety protocols. We do not comment on speculative online content.”
Yet, the airline’s press access line has been redirected. Journalists report being placed on hold indefinitely or given non-answers by generic support staff. Even employees have started referring to “VX99” as the “Vanishing X.”
What Are They Really Hiding?
Theories continue to spiral out of control. Some say it’s all a marketing stunt — a viral campaign for a new Jet2 holiday package. Others believe it’s a black-site shuttle for transferring AI hardware between experimental labs. A few even claim it’s a mobile base for extraterrestrial observation teams. The truth remains locked inside a flight that — according to public flight logs — doesn’t exist.
Yet the sightings continue.
One man in Hull claims he saw a Jet2 plane with no lights land in a field before silently taking off again minutes later. Another woman in Reykjavik heard a low drone pass over her home, and her dog has since refused to go outside.
All these tales may be pure fantasy, or they may point to something larger — a project hidden in the clouds, protected by layers of bureaucracy, fueled by shadow funding, and given life by a simple four-character code: VX99.
So, next time you book a flight on Jet2, check your ticket carefully.
If your boarding pass reads “VX99” — don’t get on.
You might come back changed.
Or not at all.
