HFY Story

Lately, I watched a lot of HFY stories, I just want to make a version of my own. Feel free to adopt and improve upon it.

Humans Were The Only Species Who Use Manned Fighter Crafts

Humans, who were the single species within the galactic coalition used manned fighter crafts as part of their military arsenal. In contrast, all other sentient species—all 219 of them—utilized various versions of unmanned drones as their small fighter crafts. Well, there have to be corrections here. Humans also use drones in fighter crafts, but on the count, more are manned instead of unmanned.

Once a species discovers that fighter craft, especially when they are still planet-bound, caused high g-force when they maneuvered, they quickly develop them to be unmanned drones as their physical bodies were unable and never designed to sustain high g-force for a prolonged time. This was more prevalent when they finally explored outside their home planet and with the absence of both atmosphere and gravity pulling them constantly downward, the g-force maneuvers of fighter crafts intensified to beyond their physical limit. But the humans? They embraced it.

Their bodies were never designed for prolonged high g-force like other species, but they just... do it. They said they just "held it" together as they maneuvered their crafts in such high g-force that it would crush any bones or exoskeleton of other species. Perhaps their home planet, Earth, a class 14 Deathworld has something to do with it. Earth has an unusually high gravity for a life-bearing planet that produces sentient, sapient life.

In their early attempts at powered flight, humans quickly discovered its usage for warfare. At first, they just used small, wooden, propeller-driven by controlled explosions winged crafts to drop some explosives at the enemy position from above. They quickly countered the bombers with fighters, winged crafts designed specifically to shoot down other winged crafts. Soon, these fighters began to fight each other in an acrobatic display now known as "dogfighting," with one maneuver in turn fighting to get in behind their opponent and shoot guns.

So many species fainted, or the equivalent of it, upon hearing that during humans' early rugged, rudimentary flights the humans brute force g-force as high as 7 g during these "dogfights." As time progressed, their technology progressed, and they began updating their fighters as well. From wooden to metal to composite material. From propeller-driven to jet-driven. Yet, one thing that remained unchanged was the human inside the craft controlling it. The only thing protecting their bodies from the intensity of high g-force was a simple flight suit. Clothing is designed to squeeze their legs and force blood from pooling on their legs. They also did some weird breathing techniques to keep blood flowing in their brains during those high g-force maneuvers.

9 g. That was the limit of most pre-space-faring fighter crafts of the humans. 9 g was enough to break even the tough exoskeleton of the Hilexian, a warrior species known for its toughness. Some humans have been known to survive something as high as 214 g, though it was a rare case. Most humans could handle something as high as 5 g. This was evident in their entertainment contraptions such as the "roller coaster," which most species agree to consider as a torture device. Most trained human fighter pilots were capable of sustaining 9 g maneuvers for a prolonged time. Their crafts were designed with this 9 g limit not because of structural or design limitations, but because any higher g-force could be fatal for the pilots as their bodies were unable to sustain the forces. Yet, they still do it anyway.

When the humans brought their attention to the stars and with it, their war machines, the fighter crafts followed as well. Their space fighter crafts, in zero gravity and zero atmosphere, were limited to 18 g in space. But of course, humans developed some g-dampening technologies for their pilots as 18 g was more than enough to kill them, yet this dampening was what limited their space fighter crafts to 18 g as with the g-dampening technology at maximum 18 g maneuver was akin to their pre-space-faring fighter craft of 9 g.
