This year commemorates the centennial of the conclusion of World War I (1914–1918). In 1914, airplanes had only existed for about ten years, yet they were already seen as game-changers in military strategy.
The aerial battles over those four short years led to one of the most rapid advancements in technology and tactics ever recorded. Below, we explore 10 bizarre aspects that defined the air war above Europe.
10. Grappling Hooks Became Unconventional Weapons

Aerial warfare during World War I was still in its early stages, leading to numerous unconventional tactics as both sides sought an advantage over the enemy. Planes at the time were slow, vulnerable, and mainly utilized for reconnaissance. However, this didn’t deter pilots from engaging in combat with one another.
Typically, pilots relied on pistols for taking shots at each other, but occasionally, they resorted to more inventive methods. They hurled bricks or grenades, and some even attempted to collide with enemy aircraft. Russian pilot Pyotr Nesterov pioneered this approach, achieving the war’s first aerial kill. Tragically, his plane disintegrated during the maneuver, and he succumbed to injuries from the crash.
Another Russian pilot, Aleksandr Kozakov, frustrated by the lack of armaments on his plane, decided to innovate. In March 1915, he tested a grappling hook to dismantle enemy planes mid-air. (Given that planes were constructed from wood, canvas, and wire, this idea wasn’t as far-fetched as it sounds.)
When his initial plan failed, Kozakov resorted to ramming his plane into the enemy. Unlike Nesterov, Kozakov and his aircraft survived the impact. Decades later, the Russians formalized this aggressive tactic into their air combat doctrine, known as taran, though that’s a tale for a different conflict.
9. Rifle Marksmanship Was Employed by Some Pilots to Shoot Down Enemy Aircraft

Amid the flood of creative (and sometimes questionable) ideas circulating among military airfields in 1914, pilots soon started carrying rifles into their cockpits. Early war aces like Frenchman Jean Navarre and Englishman Lanoe Hawker were among those who adopted this strategy.
Hawker gained notoriety among German pilots for his exceptional precision with his old-fashioned Westley Richards .300 single-shot hunting rifle. His skill was so remarkable that he could down enemy planes with just one well-placed shot, either eliminating the pilot or disabling the engine.
The sound of his rifle was nearly drowned out by the roar of the engine, leaving German planes seemingly falling from the sky without explanation. What makes Hawker’s achievements even more extraordinary is that he often faced aircraft armed with machine guns.
This naturally raises the question: “Why weren’t all planes equipped with machine guns from the beginning?” Considering that machine guns had been in existence since the mid-1800s, it seems like an obvious choice.
8. Mounting Machine Guns on Early Planes Proved to Be a Major Challenge

A significant limitation of aircraft made from canvas and wood was the lack of suitable locations to mount a machine gun. The wings were too fragile, leaving the fuselage as the only viable option. Additionally, the propeller posed a problem: how could a forward-firing gun be used without damaging it?
One approach was to position the propeller behind the pilot in a “pusher” design. However, this setup had its downsides, as it considerably diminished the engine’s power.
Some aviators experimented with mounting a machine gun at a 45-degree angle upward to avoid the propeller. Although aiming was tricky, British ace Lanoe Hawker managed to down three enemy planes in a single battle using this method. This historic triple kill earned him the Victoria Cross, Britain’s most prestigious military award.
An alternative approach involved equipping the propeller with metal deflector plates to redirect bullets. This method was first employed by France’s Roland Garros in early 1915, though the risk of unpredictable ricochets made it far from perfect.
The game-changing innovation came from Anthony Fokker, who introduced an “interrupter gear” that synchronized the gun to stop firing when a propeller blade was in the line of fire. It took the Allies months to replicate this technology, and during that time, German pilots dominated the skies, leading to significant losses among Allied airmen.
This era was dubbed the “Fokker Scourge.” However, Allied pilots faced dangers beyond just German gunfire.
7. Training Accidents Claimed More British Pilots’ Lives Than Actual Combat

Throughout most of the war, British aircrew fatalities during training exceeded those in actual combat. Training was so perilous that instructors referred to trainee pilots as “Huns” (a slang term for Germans at the time), as they were seen as just as hazardous as the enemy.
While approximately half of all British pilots lost their lives during training, German losses were only around a quarter. While this figure may still appear staggering, it’s worth noting that aviation in the early 20th century was inherently dangerous, even in peacetime.
6. A Code of Honor Prevailed Among Pilots

When a solitary British two-seater plane was ambushed by seven German aircraft, the odds of survival were slim. The crew, Justin McKenna and Sydney Sutcliffe, fought bravely, taking down four enemy planes before being shot down and killed.
However, the tale didn’t conclude there. Moved by the bravery of the two young men, a German pilot ventured over British territory to deliver a message confirming their deaths. (This act of respect wasn’t isolated.) The Germans organized a full military funeral, inviting British POWs to attend and ensuring photographs and accounts of their heroic final battle reached their families.
Both sides consistently honored those who fell in battle. When the legendary “ace of aces,” Baron von Richthofen (the “Red Baron”), was killed in April 1918, Australian forces held a dignified funeral, befitting the war’s most famous pilot.
This mutual respect also extended to living adversaries. In 1918, British pilot Gerald Gibbs, after shooting down and capturing a German crew, invited them to lunch. The German prisoners later sent him “fan mail,” requesting autographed photos as mementos of the “courageous and chivalrous foe” who had defeated them.
5. Trenches Were Targeted with Metal Darts Capable of Piercing a Man from Head to Toe

Sadly, like the knights of old, chivalry had its limits, and the harsh realities of war were always looming. While many airmen held a deep respect for their foes, they were also developing ruthless methods to eliminate them.
Before specialized bombs were invented, planes would release hundreds of sharpened metal darts, called flechettes, onto the trenches below. Initially used by the French, the Germans and British soon adopted this tactic.
These darts descended like a metallic downpour, striking fear into the soldiers below. Alongside the “chivalrous” aerial combat, these crude yet deadly weapons gave the war an oddly medieval atmosphere.
4. London Was Bombed by Airships

As death descended from the skies on the battlefield, it wasn’t long before it reached civilian areas. In today’s era of drones and precision strikes, civilian casualties from air raids are tragically common. However, during the Great War, the bombing of civilian targets was a shocking and unprecedented development that horrified the world.
While airships are now associated with benign advertising, in the early 20th century, they represented state-of-the-art military innovation. Named after a German officer, zeppelins were enormous airships deployed to bomb British cities. Initially effective, rapid technological advancements during the war soon rendered them outdated and easy targets.
Zeppelins were eventually replaced by advanced bomber planes like the Gotha. However, the concept of aerial bombardment had been established, forever changing the nature of warfare. Over 1,500 British civilians lost their lives to air raids during the war, a grim precursor to the devastation that would occur in World War II.
3. German Forces Destroyed More Than Double the Number of Allied Planes They Lost

Indeed, German aviators consistently achieved a kill ratio of two to three Allied planes for every one they lost. When factoring in their lower training accident rates and technological advancements, it’s easy to assume the Germans dominated aerial combat.
However, they were consistently outnumbered two to one. By 1918, Allied aircraft production outpaced Germany’s by nearly fivefold. To counter this, the Germans organized their planes into concentrated units called “circuses,” strategically deploying them to secure air superiority in critical areas.
Despite these efforts, it was futile. On November 11, 1918, Germany signed an armistice with the Allies, marking the official end of the war.
2. The First All-Metal Aircraft Emerged During World War I

A more successful innovation was the metal aircraft. While metal planes are commonplace today, in 1914, engines were far less powerful, necessitating the use of lightweight materials like canvas and wood.
Similar to the interrupter gear, the Germans pioneered the first all-metal plane in 1915 with the Junkers J1. This breakthrough defied conventional aeronautical engineering principles, as sheet metal was initially met with skepticism. Though revolutionary at the time, it would take decades for metal planes to surpass their wooden counterparts in performance.
1. Quadruplanes Were Engineered to Target Zeppelins

When envisioning the first major air war, most imagine biplanes engaged in fierce dogfights above the trenches. Many are also aware that monoplanes and triplanes were widely used, with the latter gaining fame through the legendary Red Baron.
However, were you aware that quadruplanes—aircraft featuring four sets of wings—were also utilized? Some of these designs were specifically crafted to target airships, with their expanded wing surface area providing stability at the low speeds needed to engage the sluggish vessels.
Both British and German forces tested quadruplanes during the conflict, but the concept never gained traction, as most models failed to deliver satisfactory performance.
