The "sound barrier" is the point at which an aircraft reaches the speed of sound, Mach 1 — roughly 1,225 km/h (761 mph) at sea level. Approaching it, aircraft meet a sharp rise in drag and turbulence that early engineers feared was an impenetrable barrier, until it was first broken in 1947.

Schlieren photography is a technique that makes differences in air density visible, allowing otherwise invisible shockwaves around fast-moving objects to be photographed. NASA used an advanced air-to-air version to capture supersonic shockwaves streaming off jets in flight.

NASA used schlieren imaging to photograph two T-38 jets from the US Air Force Test Pilot School flying about 30 feet apart at supersonic speed. The result showed how the shockwaves from the two aircraft interact — data that helps engineers design quieter supersonic planes.

A sonic boom is the loud, thunder-like sound created when an aircraft travels faster than sound, as its shockwaves reach the ground. Reducing this boom is a major goal of modern supersonic research, which is why visualising shockwaves, as in NASA's images, matters so much.

Visualising shockwaves shows exactly how pressure waves form and merge around an aircraft, guiding designs that produce softer booms. This research could one day allow overland supersonic flight, reviving an ambition not seen since fast jets like the SR-71 Blackbird.

The Bell X-1, piloted by Chuck Yeager, became the first aircraft to break the sound barrier in level flight on 14 October 1947. That milestone opened the supersonic age and led to research machines like the rocket-powered X-15.

On MiGFlug's High Altitude (Edge of Space) flights, the MiG-29 climbs to a guaranteed 17 km and often reaches 18 or even 19 km. In the past, altitudes above 20 km were possible, but a current speed limit of Mach 1.7, down from Mach 1.9, has lowered the practical ceiling.

The colder months, October through April, are best, with winter (November to February) ideal. Cold air lets the MiG-29's engines produce more thrust, so the jet climbs higher. The MiG-29 Fulcrum Edge of Space experience reaches its peak altitudes in winter conditions.

Yes. From around 17 to 19 km, near the edge of space, the sky turns dark and the curvature of the Earth becomes clearly visible. This is the signature view of the MiG-29 Edge of Space flight, a height few aircraft reach but still below the absolute altitude records set by specialised jets.

The MiG-29's top speed on these flights is currently capped at Mach 1.7, lower than the Mach 1.9 reached previously, because sustained higher speeds wore out the engines too quickly. Since speed and altitude are linked, this cap also slightly lowers the maximum height the jet can reach.

Cold air is denser and helps a jet engine generate more thrust, allowing the aircraft to climb higher. That is why MiG-29 Edge of Space flights reach their greatest altitudes in winter, and why operators recommend booking between November and February for the best chance at peak height.

Yes. Companies like MiGFlug let civilians fly in a MiG-29 without any pilot's licence. You ride in the back seat of a two-seat MiG-29UB while a professional pilot flies, and you can take the controls during parts of the flight. Almost anyone in reasonable health can book the experience.

Booking a MiG-29 flight involves choosing a flight program, submitting a questionnaire and passport scan for airbase clearance, picking a date, paying a deposit or full amount, and arranging travel and a visa with help from a specialist. The MiG-29 is operated by Russia's state-owned Sokol plant, which builds the two-seat MiG-29UB you fly in.

Over 90% of customers choose the Edge of Space flight, which climbs the MiG-29 to the upper edge of the atmosphere. The MiG-29 Fulcrum Edge of Space experience offers views of the Earth's curvature and a dark sky, making it the signature MiG-29 program.

MiG-29 flights normally take place Monday through Thursday, with Fridays sometimes possible by exception. The schedule is set by the Russian airbase that operates the jets, so dates must be coordinated and cleared in advance along with the necessary paperwork and visa.

Yes. Flying a MiG-29 in Russia requires a visa, and your passport details are forwarded to the airbase for clearance before the flight. A specialist helps arrange travel and the visa process as part of booking, since the jets operate from a Russian military facility.

A MiG-29 flight is the premium end of civilian fighter jet experiences, with the Edge of Space flight as the flagship option; current pricing is listed on MiGFlug's MiG-29 flight page. For comparison, more affordable rides such as the L-39 Albatros start around 2,500 euros, while the MiG-29 sits well above that.

No. Flights in legendary jets like the MiG-25, MiG-31, and Sukhoi Su-27 Flanker are no longer available. The MiG-29 remains the fighter jet still bookable for civilians who want the Edge of Space experience.

The MiG-29's speed on Edge of Space flights is currently limited to Mach 1.7, down from the Mach 1.9 reached in the past, because the engines wore out too quickly at higher speeds. This cap also lowers the maximum altitude, which used to reach about 22 km.

Customers typically experience around 7.5g on a MiG-29 flight, though it depends on the individual and how well they tolerate G-forces. The record reached so far is 9.2g, but passengers are not pushed that hard. A G-suit helps the body cope with the load.

Aerobatic MiG-29 programs are limited to 12 km altitude because the customer wears only a standard G-suit. Going higher requires a high-altitude flight suit, used on the dedicated Edge of Space flight that climbs to around 17 to 19 km.

Yes. Europe offers a wide range of fighter jet flights for civilians, from the affordable L-39 Albatros jet trainer to the MiG-29 Edge of Space experience. No pilot's licence is needed; you fly with a professional pilot in a two-seat aircraft and can often take the controls during the flight.

Fighter jet flights in Europe range from L-39 Albatros rides starting around 2,500 euros to the premium MiG-29 Edge of Space experience at the top end. Prices vary by aircraft and location, with jet trainers being the most accessible entry point.

The Aero L-39 Albatros is the most affordable and popular fighter jet experience, with European rides starting around 2,500 euros. The L-39 is the world's most popular fighter jet experience thanks to its blend of jet performance and accessible price.

Booking a fighter jet flight is straightforward: you contact the operator through a contact or booking form, and a team guides you through choosing an aircraft, picking a date, and completing the paperwork. No flying experience is required; the experience is designed for first-time civilian flyers.

European fighter jet experiences include jet trainers like the L-39 Albatros and combat jets like the MiG-29. The L-39 offers an accessible, aerobatic introduction, while the MiG-29 delivers the flagship Edge of Space climb toward the upper atmosphere.

Civilian fighter jet flights are offered mainly in three regions: the US East Coast, the US West Coast (including Texas), and Europe. Each region offers different aircraft and price points, ranging from accessible jet trainers like the L-39 Albatros to high-performance fighters.

The Aero L-39 Albatros is the most popular and affordable fighter jet experience, available across several regions. The L-39 is the world's most popular fighter jet experience because it combines genuine jet performance with a relatively accessible price.

Yes. Fighter jet experiences are available on both the US East Coast and the US West Coast, including Texas. Options range from jet trainers to fast jets, and some locations offer warbirds; you can, for example, look into whether you can fly an F-14 Tomcat.

The MiG-29 is flown in Russia, where civilians can book the famous Edge of Space experience that climbs toward the upper atmosphere. It is the flagship of civilian fighter flying, distinct from the jet-trainer and warbird flights offered elsewhere.

Fighter jet ride prices depend heavily on the aircraft and region. Jet trainers like the L-39 Albatros are the most affordable entry point, starting around 2,500 euros in Europe, while combat jets such as the MiG-29 Edge of Space flight sit at the premium end. Each region publishes its own pricing by aircraft.

The widely recognised boundary is the Kármán line, which lies at an altitude of 100 kilometres (about 62 miles) above sea level. It marks the conventional border between Earth's atmosphere and outer space, used by aviation and aerospace bodies as the dividing line between aircraft and spacecraft territory.

The Kármán line is the boundary between Earth's atmosphere and outer space, set at 100 km (62 mi) altitude. Above it, the air is too thin for conventional aircraft to generate lift, so an object must travel at orbital speed to stay aloft. It is the standard definition of where space begins.

A fighter jet like the MiG-29 can climb to around 17–19 km on an Edge of Space flight — high in the stratosphere but still far below the 100 km Kármán line. From that altitude you can see the curvature of the Earth and a darkening sky, the closest a MiG-29 experience gets to true space.

Not in level flight — but people have fallen from near it. Daredevils have ridden balloons to the stratosphere and jumped from the edge of space, free-falling back through the atmosphere. Reaching orbital space itself, however, still requires a rocket to achieve the necessary speed and altitude.

Above about 100 km the atmosphere is so thin that wings can no longer generate meaningful lift, no matter how fast a plane flies. To stay up beyond that point an object must move at orbital velocity, which is the realm of spacecraft. That physical limit is why the Kármán line defines the edge of space.

The "ground speed check" is a famous anecdote from SR-71 pilot Brian Shul's book "Sled Driver." As various aircraft asked air traffic control for their speed, Shul's crew requested a check too — and the controller reported a ground speed well over 1,800 knots, far faster than anything else in the sky.

Brian Shul was a US Air Force pilot who flew the SR-71 Blackbird and later wrote the acclaimed book "Sled Driver" about his experiences. A survivor of a fiery Vietnam-era crash, he became celebrated for his vivid storytelling and photography of the world's fastest jet.

The SR-71 was the fastest air-breathing crewed aircraft ever, cruising above Mach 3 — roughly three times the speed of a typical airliner and faster than most fighter jets. In the famous radio story, it left an F/A-18 and other aircraft far behind in any speed comparison.

Among jet-engine aircraft, yes — but the rocket-powered North American X-15 flew far faster, reaching nearly Mach 7. The SR-71 remains the fastest air-breathing jet, while pure rocket planes hold the absolute speed records.

No one can fully verify it, and even Shul presented it as a great tale rather than documented fact. Still, it captures the real pride of Blackbird crews, who genuinely flew the fastest jet on Earth and loved reminding other pilots of it.

The SR-71 combined record-breaking speed, striking looks and an aura of secrecy that captivated aviators and the public alike. Decades after retirement it remains a legend, regularly ranked among the most beautiful and impressive aircraft ever built.

Flying a fighter jet is expensive but possible for civilians. A MiG-29 supersonic experience flight starts at around EUR 13,500 for 45 minutes, or EUR 11,500 for a 25-minute non-supersonic flight. Military operating costs are far higher — Austria calculated roughly EUR 70,000 per flight hour for its Eurofighters. You can even fly a fighter jet yourself through experience providers.

Air Force One, the Boeing VC-25A (a modified 747-200), costs about USD 206,337 per flight hour according to figures released under the US Freedom of Information Act. That makes presidential travel extremely expensive — one 2013 overseas trip reportedly cost taxpayers nearly USD 8 million.

Fighter jets are costly to operate because they burn huge amounts of fuel and require intensive, specialised maintenance. Supersonic jets consume far more fuel than subsonic trainers, which is why trainer flights are significantly cheaper. Crews, spare parts, and runway operations all add to the high hourly cost.

The Northrop B-2 Spirit stealth bomber is widely regarded as the most expensive aircraft ever built, and it is correspondingly costly to operate. Other expensive aircraft to run include Air Force One and the E-4 "Nightwatch" airborne command post.

The E-4 "Nightwatch" is a militarised Boeing 747 that serves as a US airborne command-and-control centre, designed to keep national leadership operational during a crisis. It is among the most expensive aircraft to operate and has been seen flying to events such as the Davos World Economic Forum.

Passengers fly with highly experienced professional test pilots. On MiGFlug's flights in Russia, guests are flown by pilots such as Yuri Polyakov, Sergey Kara or Andrey Pechionkin. They are seasoned aviators who handle the demanding parts of the flight while letting the passenger take the controls when it is safe.

These MiG-29 flights operate from Nizhny Novgorod, a Russian city about a short domestic flight from Moscow. Guests are collected from their hotel by an interpreter on flight day and driven to the airbase, where they fly the MiG-29 Fulcrum Edge of Space experience with a professional pilot.

Yes. Flights are conducted in the twin-seat MiG-29UB by very experienced test pilots, with the passenger flying under close supervision. Extensive briefing, medical paperwork and the pilot's control over the flight's intensity all contribute to a professionally managed experience, even though the jet is a genuine supersonic fighter.

Both. An experienced pilot manages takeoff, landing and safety, but passengers get hands-on time at the controls during the flight and can experience manoeuvres and aerobatics. For those wondering whether ordinary people can do this, the answer is yes — no licence is required, as covered in guides on whether anyone can fly a fighter jet.

The pilots are highly experienced professionals, many of them test pilots, with thousands of hours on the MiG-29. Flying paying guests to the edge of space and through high-G manoeuvres demands exactly that level of skill, which is why the flights are entrusted only to seasoned aviators based at the airbase.
