In the early 1950s, dragsters were coming into their own as uniquely designed cars, specifically for drag racing. The SDTA’s rules required the driver’s cockpit to enclose the driver on the sides, bottom, and rear. A rollbar, seatbelt, and fire extinguisher were also mandated. There were no restrictions on fuel. Just prior to launch, the driver’s right hand is pressurizing the fuel system with a hand pump. There were no guardrails between the competitors and spectators on the wide runway.
