Jack McClure, affectionately known as « Captain Jack, » carved an indelible niche in the annals of drag racing history. Far from conventional Funny Cars or thunderous Top Fuel dragsters, McClure chose a path uniquely his own: a rocket-powered go-kart designed for pure, unadulterated speed and spectacle. He wasn’t just a racer; he was a showman, a daredevil whose incredible feats behind the wheel of « Smokey, » his hydrogen peroxide-fueled machine, captivated audiences and pushed boundaries. Reaching speeds well over 200 miles per hour in a vehicle barely larger than an amusement park ride, McClure embodied the raw excitement and danger that defined a golden age of exhibition drag racing. His legend, steeped in fire, smoke, and blistering speed, continues to resonate, proving some thrills are timeless.
The Rocket Age on the Drag Strip
The 1960s and 70s were a period of intense innovation and showmanship in drag racing. Alongside conventional classes, exhibition vehicles emerged, designed not just to win races but to mesmerize spectators. Jet-powered cars, wheel-standers, and increasingly, rocket-powered machines became main attractions, drawing massive crowds eager to witness cutting-edge performance and daring. Within this high-octane landscape, Jack McClure found his calling. Unlike internal combustion engines, rocket propulsion offered instantaneous, immense thrust, creating a visual and auditory spectacle unlike anything else. He understood that pure speed, combined with danger and theatrical presentation, was the ultimate crowd-pleaser.
Smokey: A 200-mph Testament to Daring
At the heart of Captain Jack’s legend was « Smokey, » his iconic rocket-powered go-kart. This was no ordinary kart; it was a minimalist marvel of engineering and bravery. Its core features defined its audacious performance:
- A simple, robust chassis provided the foundational strength.
- A hydrogen peroxide rocket engine, mounted directly behind the driver, generated immense, instantaneous thrust.
- The catalyst-induced decomposition of hydrogen peroxide created superheated steam for propulsion.
- A stripped-down, purely functional design focused solely on speed, leaving the driver exposed.
- The capability to regularly exceed 200 mph, a staggering achievement for its size and era.
The experience for the audience was visceral: a plume of white steam, a deafening roar, and then, a blur of motion as Smokey rocketed down the quarter-mile. McClure’s runs were an astonishing feat for any vehicle, let alone one with such an exposed driver and rudimentary chassis, making him an integral, heroic part of the machine.

Before each run, he would engage with the crowd, building anticipation and sharing stories, cementing his image as the friendly, yet fearless, showman. But the real spectacle began when Smokey fired up. The hydrogen peroxide rockets would emit a cloud of dense white steam, often accompanied by flames, creating a dramatic visual that filled the drag strip. The sheer noise was immense, a piercing roar that signaled the unleashed power of the rocket. McClure understood the theatricality of his runs, carefully orchestrating the drama from the moment he donned his helmet to the final braking maneuver. He mastered turning raw speed into riveting entertainment.
