Understanding the North American Eagle Project
The North American Eagle jet car was built as a rolling laboratory for extreme land speed records. Based on a modified F-104 Starfighter airframe, the project combined vintage engineering with modern composites and a General Electric J79 turbojet. The goal was simple on paper: push past 700 mph on a dry lake bed and rewrite the record books.
Engineers working on the project emphasized incremental testing before full runs. Each attempt followed detailed checklists, telemetry reviews, and weather checks. Yet even with careful planning, the margin for error at such speeds is razor thin.
The Fatal Crash and Immediate Aftermath
On the day of the crash, the team rolled the North American Eagle to the runway and prepared for a record attempt. Acceleration appeared normal on video until the car suddenly swerved, lifted, then violently broke apart. Witnesses reported loud structural noises just before loss of control, pointing to a mechanical failure at the worst possible moment.
Emergency crews responded quickly, but Jessi Combs could not be saved. The impact scattered debris across the desert and halted ongoing record campaigns for months. The National Transportation Safety Board later classified the event as an accident rooted in mechanical failure.
Technical Investigation and Root Cause Analysis
Investigators focused on the point where the front axle and wheel assembly failed. They concluded that a combination of fatigue and a wheel bearing issue led to sudden loss of steering. Once the car left the ground, there was no way to recover before impact.
- Wheel bearing showed signs of overheating and spalling
- Front axle fractured under high dynamic loads
- No evidence of pilot error or control malfunction
- Design did not fully account for repeated high-G stresses
Safety Protocols and Industry Response
High-speed land racing has always carried inherent risks, but the Jessi Combs jet car crash prompted organizations and teams to revisit safety standards. Track protocols for remote areas, driver communication, and abort procedures were reviewed in detail across the industry.
Teams now emphasize redundant checks on critical rotating components and stronger data links with chase vehicles. The community has also pushed for better real-time telemetry to catch developing faults before they become catastrophic.
Legacy and Influence on Future Record Attempts
Despite the tragedy, the North American Eagle project contributed valuable data on jet car dynamics at extreme speeds. Engineers have used findings from the crash to refine designs for next generation record vehicles, focusing on durability and real time diagnostics.
Jessi Combs remains a symbol of courage and technical curiosity in motorsport. Her work continues to inspire new generations of engineers who aim to balance ambition with rigorous safety practices.

FAQ
Reader questions
What exactly happened during the Jessi Combs jet car crash?
The crash occurred when the North American Eagle lost steering after a front axle and wheel bearing failure, causing the car to swerve, lift off the ground, and break apart at high speed in the Alvord Desert.
What caused the mechanical failure in the jet car?
Investigations determined that a wheel bearing overheated and failed, leading to fatigue and fracture in the front axle under extreme loads during acceleration.
What safety changes have been implemented for land speed record attempts?
Teams and organizations have tightened component inspection protocols, added redundant telemetry systems, and defined clearer abort criteria to reduce risk in future record runs. Engineers and drivers view calculated risk as part of pushing technical boundaries, and each incident drives improvements in materials, design, and real time monitoring technologies.
