The vast majority of aviation enthusiasts are well aware of the fairly straightforward principle that photographing aircraft from public land is usually legal. However, there is a very specific exception to this rule that most planespotters are well aware of. Federal prosecutors have indicated that Tianrui Liang, a 21-year-old Chinese national studying aeronautical engineering at the University of Glasgow, crossed into the United States on a valid B1/B2 visa, traveled to several military sites, and photographed aircraft at Offutt Air Force Base in Nebraska, which is home to the United States Strategic Command. He was ultimately arrested at John F. Kennedy International Airport (JFK) in New York on April 7, 2026, while allegedly trying to leave for Scotland.

The legal issue is not just whether Liang stood on public land. Prosecutors charged him under a specific U.S. statute (18 U.S.C 795), a little-known law that bars photographing, sketching, mapping, or otherwise visually recording certain vital military installations or equipment without permission from the relevant commanding officer. According to federal filings reported by multiple outlets, Liang allegedly photographed aircraft, including the RC-135 reconnaissance platform and E-4B Nightwatch aircraft, which are known as the Doomsday aircraft. He reportedly said that these photos were for a personal collection, but he also acknowledged that he was well aware that photographing the aircraft was highly illegal. For aviation enthusiasts, this case draws a sharp line between routine spotting and national-security scrutiny.

What Is The Need For This Kind Of Law?

From a high-level strategic perspective, it is not all that hard to understand why the United States would want to have a law like 18 U.S.C. 795 because the importance of military secrecy to the American government cannot be understated. This is not just about hiding what exists, but rather about controlling what adversaries can learn from patterns, timing, configuration, and location. A single photo of an aircraft may seem harmless, especially to an aviation enthusiast, but repeated photographs can reveal deployment cycles, maintenance status, upgrades, sensor packages, defensive systems, or overall operational readiness.

For a dynamic, capable, and carefully developed aircraft like the E-4B or RC-135, even small visual details can help foreign intelligence services understand how the US manages command-and-control, nuclear continuity, surveillance, and crisis-response capabilities. This unique law also creates a clear enforcement tool before conduct reaches traditional espionage levels. Prosecutors do not have to prove that someone stole classified documents or transmitted secrets directly to a foreign government.

They can also act when a person records restricted military assets without permission of any kind. That is quite useful in this world, where open-source intelligence is quite powerful and foreign actors are quite capable. Foreign information collectors may operate under the cover of tourism, student travel, or hobbyist planespotting. At the same time, the law reflects a point of tension with existing legislation. The US generally permits photography in public places, but military installations are treated differently because strategic advantage often depends on denying adversaries small, cumulative pieces of information.

What Incident Brought This Unique Law To Light?

This unique piece of legislation was brought back directly into the spotlight by the situation involving Tianrui Liang, a 21-year-old Chinese national who had been visiting the United States. He was a highly-regarded aeronautical engineering student who had been employed at the University of Glasgow. According to federal filings, Liang entered North America through Vancouver International Airport (YVR) on March 26, 2026, and he met another student shortly thereafter.

From there, he crossed into the United States, and he drove through several states while visiting or seeking out military aviation sites. His trip included a visit to Offutt Air Force Base in Nebraska, one of the most sensitive American military installations because it is home to the US Strategic Command. At Offutt, investigators say that Liang got out of a car on a public road and photographed aircraft on the flight line, including an RC-135 reconnaissance aircraft and an E-4B “Nightwatch.” The airborne command post has been routinely referred to as the “Doomsday plane.”

The affidavit from this incident, filed by the Federal Bureau of Investigation, said that he used planespotting websites to identify locations and later told investigators that the images were exclusively for his personal collection. Nonetheless, he allegedly also acknowledged that while photographing aircraft in the sky was legal, he knew that photographing the aircraft in question was not legal. Liang was later arrested at JFK Airport on April 7 while he attempted to return to Glasgow. The case became notable because it showed that public-road photography can still trigger federal charges when vital military installations are involved.

What Consequences Will Liang Face?

If convicted under this piece of legislation, Tianrui Liang faces a handful of serious federal penalties, including up to a year in prison, a massive fine, or potentially both. The statute itself has not been written in the form of a major espionage charge on its own. Rather, it is a narrower offense focused on unauthorized photography or visual documentation of designated military installations and equipment. That ultimately matters because prosecutors do not need to prove that Liang was a Chinese spy to pursue the case, according to Fox News.

Rather, their only obligation is to prove that he unlawfully photographed protected military assets without appropriate permission. The most immediate consequence here for him is detention and prosecution in federal court. Liang was first released by a federal magistrate judge in New York City, but Nebraska prosecutors successfully appealed, arguing that he was a very serious flight risk. The Justice Department has said that he was taken into custody by US Marshals on April 10, and he has been transferred to Nebraska.

Beyond prison or fines, the practical and more likely consequences are set to be severe. Liang will likely face visa cancellation, deportation, and serious reputational damage. Even without a serious espionage charge on the table, the case places him inside a national-security investigation involving sensitive aircraft, foreign travel, and alleged efforts to leave the country after FBI contact.

Do Other Nations Have Similar Laws?

The United States is rather unusual in how directly it has a regulation that targets unauthorized photography of vital military installations, but the broader concept is common. Many states restrict photography, filming, sketching, drone use, or surveillance around military sites because modern intelligence collection often relies on ordinary-looking images rather than stolen classified files. The United Kingdom has a similar framework under the National Security Act of 2023.

That legislation treats prohibited places as sensitive national-security sites and makes clear that illicit activities can include everything from photographs to videos and other recordings. In serious cases involving conduct prejudicial to UK safety or interests, penalties can be as drastic as 14 years in prison. Australia’s legal codes are even more specific, with Section 82 of the Defense Act of 1903 making it an offense to make a photograph, sketch, drawing, picture, or painting of a defense installation without lawful authority.

That rule can allow for the seizure or forfeiture of photographic equipment and materials. Canada’s regime is framed more broadly around espionage and protected information, including everything from sketches, plans, models, notes, documents, and information related to munitions or national security.

What Lessons Should Be Learned By Photographers?

There are a few major messages for photographers to keep in mind here. The first is that public land is not always a complete shield for photography activities when military facilities are involved. In most ordinary aviation spotting, taking photos of aircraft from public roads, parks, or viewing areas is not automatically illegal. However, sensitive military bases operate under a different legal and security environment, especially when aircraft are parked, undergoing maintenance, or located inside a designated installation.

Photographers should assume that military airfields, nuclear-related sites, command-and-control facilities, and restricted zones require extra caution. Warning signs, fences, patrols, and prior reports of law enforcement scrutiny should be taken very seriously. Foreign visitors should be especially careful, as harmless hobby activities can be interpreted through a national-security lens.

The safest approach is to research local rules, avoid photographing inside base boundaries, avoid trespassing, comply calmly with law enforcement, and seek permission where required. For serious spotters, the best photograph is not worth an arrest, visa problem, or federal charge.

What Is Our Bottom Line?

At the end of the day, it is not remotely surprising that the United States government has this kind of national security law. At the same time, it can make a lot of sense why an aviation photographer might think that taking photographs on public land is fully permitted under the law.

Unfortunately, this is not the case, and even recreational aviation enthusiasts would be wise to keep in mind the major consequences of choosing to take photographs in these kinds of locations. In Liang’s case, which undeniably has led to extensive speculation because of his status as a Chinese national, espionage questions have been brought into play.

The need to preserve national secrets, especially relating to some of the US’s most classified programs, cannot be understated. Therefore, it is important for these kinds of incidents to be discussed and widely circulated, so that amateur photographers will not accidentally wander into a situation where they are facing federal charges.
