Bartosz Ciechanowski's interactive articles are long-form explanations of science and engineering topics in which the reader manipulates a live simulation rather than only reading text or looking at static diagrams. The clearest example is his December 17, 2024 article "Moon," where you drag the Moon to change your viewing angle, move a slider to control date and time, and drag a figurine on a globe to see the sky from different places on Earth. The approach suits readers who want to build intuition for spatial or physical systems — orbits, geometry, mechanics — and who are willing to spend time experimenting with controls instead of reading a linear argument.

What makes these articles "interactive"

The defining feature is that the explanation is carried by a model you operate, not by prose alone. In the Moon article, the page offers several distinct kinds of control, each tied to a different concept:

• Drag to rotate the view. In the space view, you can drag the Moon around to change your point of view and see its craters and mountains from various angles — a freedom of motion you don't have from Earth.
• Sliders for time. By dragging sliders you can watch how the Moon's position in the sky changes across days and hours of your local time.
• A panorama you can drag. The sky view lets you adjust your viewing direction to see the breadth of the sky both above and below the horizon, with a small arrow guiding you to the Moon's position.
• A location figurine. You can drag a small figurine on a globe in the bottom-right corner to see how the sky looks at that location on Earth. If your browser allows it, clicking or tapping a button places the figurine at your current location.

Each control maps to a variable in the underlying model, so manipulating it is equivalent to asking "what if this changed?"

How the Moon article builds understanding step by step

The article doesn't hand you the full picture at once — it deliberately starts with a view you can't have in real life, then narrows toward everyday experience.

1. Start from space. You first see the Moon in its sunlit glory, free to pan the camera around it. This establishes the object itself.
2. Move to the sky. The article then simulates the Moon's travels as seen from the ground, where you can drag the panorama and adjust time.
3. Zoom and lock on the Moon. Because the Moon is small and shifting, the camera zooms in and locks its position on it. At this scale you can notice that across a single day the Moon seems to rotate, and over many days it visibly wobbles.
4. Connect the wobble to a real consequence. Those wobbly variations let us occasionally see hidden parts on the edges of the Moon, but the Moon ultimately shows us only one of its sides.

The sequence matters: the space view gives you a mental model of the whole system, and the sky view shows why that system looks so limited and confusing from where you actually stand.

Why manipulation helps where text doesn't

The core difficulty in the Moon article is that the Moon's apparent motion is slow, small, and entangled with your own position and the time of day. Text can state these facts, but it can't let you feel the trade-offs. The simulation does three things prose can't:

• It separates variables. Time, viewing direction, and observer location are independent controls, so you can hold two constant and vary the third.
• It makes the invisible visible. The panorama extends below the horizon, so you can see where the Moon is when it isn't in your sky.
• It rewards re-reading. The article notes that the whole picture "may all feel quite overwhelming at the moment," and that the pieces fit together eventually — the design assumes you'll return and re-manipulate.

Scope and how to use these articles

The site describes itself as "interactive articles about science and engineering," and its keywords point to physics, math, engineering, and STEM generally, so the Moon piece is one instance of a broader format rather than a one-off. To get the most out of any of them:

• Read the short framing text first to learn what each control does, then experiment before continuing.
• Change one control at a time so you can attribute what you see to a specific variable.
• Expect to loop back — the articles are built for repeated passes, not a single read.

If you prefer a fixed narrative you can read straight through, this format will feel slow; if you learn by poking at a system until it makes sense, it's built for exactly that.

Falcon BMS is a free combat flight simulator built around the F-16, and its own site describes it as "the best free flight simulator for military aviation." It is aimed at players who want study-level F-16 systems, a persistent war that continues whether or not you are flying, and a community that shares mods and missions. If you want a lighter, arcade-style jet game, this is not that; if you want to learn an F-16 cockpit and fly inside a dynamic campaign, it is the core of what the project offers.

What Falcon BMS actually is

Falcon BMS is a community-developed simulator distributed by the Benchmark Sims team, made up of volunteers from around the world who "dedicate our time and knowledge" to the project. The site presents it as a full simulator rather than a single aircraft add-on, with its own flight model, systems, weapons, AI, and campaign layer.

The name carries a legacy: BMS builds on the Falcon 4.0 lineage, and the current release line has moved through Falcon 4.38 and its updates. The site's news feed lists "Falcon 4.38 is here" (Jul 1st, 2025), "Falcon BMS 4.38 Update 1 is out!" (Nov 11th, 2025), and "Falcon BMS 4.38.1 Hotfix is out" (Dec 16th, 2025), so the project is actively maintained rather than frozen.

Key features the site highlights

The homepage groups its selling points under a Features section. These are the ones that matter most when deciding whether to invest time in it:

• Dynamic Campaign — "Be part of a war and live through it from a simple pilot to a commander in chief." You can fight from the air and coordinate land and sea battles, and your role can scale from a single pilot up to command.
• Precision Aerodynamics — the team says it has "gone far to give you the right F-16 flight dynamics and feeling on the stick," modeling aerodynamics and flight control systems together.
• F-16 Systems Realism — multiple F-16 variants and countries, with authentic avionics, weapons, and countermeasures set in a 2000-era warfare context. Virtual Reality is supported, which the site says makes you "feel like you are really there."
• Advanced AI — ground, air, and sea units are modeled so enemies use tactics and strategies while allies support you in combat.
• Community Driven — flying together, sharing experiences, mods, and missions, and contributing to ongoing development.
• Additional planes — you can fly other aircraft with custom 3D cockpits; the F-15C is specifically called out as available "with advanced systems and flight dynamics."

Aircraft beyond the F-16

The F-16 is the center of the simulator, but it is not the only option. The site states that other planes can be flown with custom 3D cockpits, and names the F-15C as an example with advanced systems and flight dynamics. That matters if you are deciding between Falcon BMS and a simulator that locks you to one airframe: here the F-16 is the reference aircraft, and additional types extend what you can fly.

How to get it and where to go next

The homepage provides a direct path into the project:

1. Download — use the "Download Now" link on the homepage to get the simulator.
2. Check the trailer — the Trailer Video section shows Falcon BMS in action before you commit disk space and setup time.
3. Read the FAQ — the site's navigation includes an F.A.Q., which is the place to check before asking basic setup or compatibility questions.
4. Follow updates — the Latest News section carries release and hotfix announcements, so you can see whether you are on the current version.
5. Join the community — the site links to a Forum and a Sign In option, and the Community Driven feature points to multiplayer flying and sharing mods and missions.

Who this is for

Falcon BMS fits you if you want a free, community-maintained F-16 simulator with a dynamic campaign, realistic systems, and an active multiplayer and modding scene. It fits less well if you want a short, guided, single-player experience without learning cockpit procedures. The site's own framing — "the best free flight simulator for military aviation" — sets the expectation: this is a long-term sim you grow into, not a quick game you finish.

A dynamic campaign in Falcon BMS is a persistent, evolving war that reacts to what you and the AI do, rather than a fixed sequence of scripted missions. You start as a single pilot and can rise to commander-in-chief, directing air, land, and sea operations. Falcon BMS is built around this feature, so if you want a flight sim where the battlefield changes because of your choices, it's the core reason to try it. Expect a steep learning curve and a real time investment before the campaign makes sense.

What "dynamic" actually means

In a scripted campaign, mission order, targets, and outcomes are largely predetermined. You fly the mission, it ends, and the next one starts from a fixed state.

In Falcon BMS's dynamic campaign, the war keeps running whether or not you're flying:

• The front line moves. Ground units advance or retreat based on combat results.
• The war persists. Events continue across the theater, not just in the mission you're in.
• Your actions feed back in. Strikes, patrols, and support missions change what the AI does next.
• The AI acts on its own. Enemy units use tactics and strategies to challenge you, while allied units support you in combat, per the site's description of its Advanced AI.

The result is a battlefield that feels alive: a bridge you destroy stays destroyed, and a sector you weaken may be exploited by friendly forces.

Your role: from pilot to commander

The campaign is designed around progression in responsibility. As the site puts it, you "be part of a war and live through it from a simple pilot to a commander in chief," fighting from the air while coordinating "massive land and sea battles to drive your team to victory."

In practice that means two layers of play:

You can stay in the cockpit and let the war run around you, or take on more control over how your side fights. The campaign supports both.

How the campaign state persists and reacts

The campaign tracks the theater as a whole. Your missions and the AI's ongoing operations both change that state, and the changed state shapes the next set of missions you're offered. Because the war doesn't pause, a decision to skip a sector or focus your effort elsewhere has consequences you'll see later.

This is the key difference from static campaigns: you're not replaying a fixed story, you're participating in an ongoing conflict where outcomes accumulate.

What Falcon BMS gives you around the campaign

The dynamic campaign sits inside a broader simulation, and these pieces matter for how it plays:

• F-16 flight dynamics and feel. The BMS team modeled aerodynamics and flight control systems for a realistic stick-and-rudder experience.
• F-16 systems and weapons. Multiple F-16 variants and countries, with avionics, weapons, and countermeasures set in a 2000-era warfare context.
• Virtual Reality support. The site notes VR is part of the mix for immersion.
• Other aircraft. You can fly other planes with custom 3D cockpits; the F-15C is available with advanced systems and flight dynamics.
• A large community. Players fly together and share experiences, mods, and missions, and contribute to ongoing development.

What a new player should expect

• Complexity is high. Authentic avionics and systems mean study time before you're effective.
• The campaign rewards patience. Its value shows up over many missions, not in one sortie.
• You don't have to command immediately. Start as a pilot, learn the aircraft, and let the war's behavior teach you how the theater responds.
• The community is a resource. Given the depth, flying with others and using shared missions and mods shortens the learning curve.

If you want a flight sim where the war is a living system rather than a mission list, Falcon BMS's dynamic campaign is the feature to evaluate first. If you'd rather have a guided, predictable sequence of missions, a scripted campaign will suit you better.
