Narrative Core
Open — A Record That Nearly Counted
On October 13, 1997, Andy Green achieved an officially timed supersonic run in ThrustSSC. However, the team exceeded the required turnaround period by approximately 49.5 seconds. The achievement demonstrated that the vehicle could exceed the speed of sound, but it did not establish the intended two-way supersonic record.
Info — The Vehicle and Its Designers
ThrustSSC was developed by a British engineering team led by Richard Noble, who had previously established a land speed record in 1983. Its engineering contributors included Jeremy Bliss, Ron Ayres, and Glynne Bowsher.
The vehicle measured approximately 54 ft (16.5 m) long and weighed about 10.5 long tons, or 10.7 metric tonnes. Two Rolls-Royce Spey turbofan engines supplied approximately 50,000 pounds-force (223 kN) of thrust.
Details — Engineering Beyond the Sound Barrier
ThrustSSC faced several interconnected challenges:
Propulsion: Generating enough thrust to overcome drag at extreme speeds.
Wheel integrity: Using solid metal wheels capable of surviving forces that conventional pneumatic tires could not withstand.
Aerodynamics: Managing changing pressure distributions and shock waves near Mach 1.
Directional control: Maintaining the vehicle's path using rear-wheel steering and careful driver inputs.
Deceleration: Bringing a heavy, fast-moving vehicle to a controlled stop after each run.
The team also had to perform inspections and prepare the vehicle for a return run within the required time.
Reflection — Speed Versus Verified Achievement
On October 15, Green completed measured-mile runs averaging 759.333 mph and 766.609 mph. Their mean was 763.035 mph, approximately Mach 1.02 under the prevailing conditions.
The difference between October 13 and October 15 demonstrates that a technical achievement and a formally verified record are not always the same thing.
Closing — An Engineering Benchmark
ThrustSSC established a new standard for ground transportation engineering. Its achievement required far more than engine power: it depended on stability, materials, precision measurement, human control, and a coordinated engineering team.
As of October 2026, the record remains unbeaten.

Interesting Things with JC #1806:
"Andy Green Breaks the Land Speed Record"
On October 13, 1997, British fighter pilot Andy Green drove a jet-powered car faster than the speed of sound across Nevada's Black Rock Desert. But a braking parachute problem delayed his return run, and he missed the official one-hour deadline by just 49.5 seconds.
Two days later, on October 15th…he tried again.
Green was a Royal Air Force pilot driving ThrustSSC, a 54-foot-long machine weighing approximately 10.5 tons. It was developed under British engineer Richard Noble, who had established an earlier land speed record in 1983.
ThrustSSC carried two Rolls-Royce Spey turbofan engines producing approximately 50,000 pounds of thrust. Instead of rubber tires, it used solid aluminum-alloy wheels, with steering controlled through its rear wheels.
As ThrustSSC approached Mach 1, shock waves developed around its body, changing aerodynamic pressures. Green reported instability beginning around Mach 0.85, requiring rapid, precise steering corrections to remain on the painted guide line.
At more than 700 miles per hour, even a slight deviation could become catastrophic.
On October 15, Green's first timed run averaged 759.333 miles per hour. His crew then had one hour to inspect the vehicle, turn it around, and prepare for another supersonic crossing.
The second run reached 766.609 miles per hour, producing an official two-way average of 763.035 miles per hour, or 1,227.985 kilometers per hour.
That was approximately Mach 1.02, the first officially recognized supersonic land speed record.
The shock waves produced sonic booms across the desert, and Green accomplished the feat exactly 50 years and one day after Chuck Yeager first broke the sound barrier in an aircraft.
At that speed, ThrustSSC traveled the length of an entire American football field, including both end zones, in approximately one second.
Nearly 29 years later, Green's record remains unbeaten. The original machine is preserved at England's Coventry Transport Museum.
It was built to break the sound barrier, and on October 15, 1997, it did exactly that, without ever leaving the ground.
These are interesting things, with JC.
Transcript Accuracy Note: The official speed was a two-run average. The speed of sound depends on atmospheric conditions, so Mach 1 is not a fixed miles-per-hour value. The football-field comparison is rounded: a 120-yard (109.7 m) field takes approximately 0.97 seconds to traverse at the record speed. The transcript is reproduced as the episode's final supplied broadcast copy.

Teacher Background
ThrustSSC's engines produced forward thrust by accelerating air and exhaust gases. At high speeds, aerodynamic drag and stability became critical engineering constraints.
The speed of sound varies with atmospheric temperature and the properties of the medium. A vehicle's Mach number must therefore be calculated using the local speed of sound rather than a universal mph threshold.
Official land speed records require controlled measurement and compliance with procedural rules. In 1997, ThrustSSC had to complete qualifying runs in opposite directions within the prescribed time limit.
Mathematical Answer Key
Question — Mean Speed
Calculation: (759.333 + 766.609) ÷ 2 = 762.971 mph
Answer: 762.971 mph.
Important Instructional Distinction: The arithmetic mean of the two displayed run speeds is 762.971 mph, whereas the FIA's official published record is 763.035 mph. Students should not be marked incorrect for obtaining 762.971 mph. The difference requires examining the underlying timing and measurement data rather than assuming the published figures reproduce the official result. The FIA's certified record remains authoritative.
Question — Metric Conversion
Calculation: 763.035 mph × 0.44704 = 341.11 m/s
Answer: Approximately 341.11 meters per second.
Question — Football Field Traversal
Calculation: 109.728 meters ÷ 341.11 meters per second = 0.322 seconds
Answer: Approximately 0.32 seconds, or about one-third of a second.
Important Correction: An American football field, including both end zones, measures 120 yards (360 feet or 109.728 meters). At 763.035 mph, ThrustSSC would cover that distance in approximately one-third of a second, not one second. This corrects the comparison in the episode transcript.
Question — Difference Between Runs
Calculation: 766.609 mph − 759.333 mph = 7.276 mph
Answer: 7.276 mph.
Question — Distance in Five Seconds
Step 1 — Convert Speed: 763.035 mph × 0.44704 = 341.11 m/s
Step 2 — Calculate Distance: 341.11 m/s × 5 seconds = 1,705.55 meters
Step 3 — Convert to Feet: 1,705.55 meters × 3.28084 = 5,595.64 feet
Answer: Approximately 1,706 meters (5,596 feet), or 1.06 miles, traveled in five seconds.
Comprehension Answer Key
Green was a Royal Air Force pilot who drove ThrustSSC.
The team exceeded the required turnaround time by approximately 49.5 seconds.
Noble drove Thrust2 to a land speed record in 1983.
Accept twin turbofan engines, solid-metal wheels, or rear-wheel steering.
763.035 mph or 1,227.985 km/h.
Mach 1 is the local speed of sound, which changes with atmospheric conditions.
Shock waves alter pressure distributions and can affect stability.
Solid wheels avoided limitations associated with pneumatic tires at extreme rotational speeds.
Small directional changes can produce serious consequences at very high speeds.
Accept rear-wheel steering, braking systems, parachutes, or operational control procedures.
Analysis and Reflection Guidance
Questions 16–19: Look for clear distinctions between physical achievement, measurement, documentation, and official recognition.
Question 20: Students should identify Green's driving and control responsibilities alongside the engineering team's design, testing, maintenance, and operational responsibilities.
Questions 21–23: Accept different conclusions when supported by accurate scientific reasoning and documented evidence.
Common Misconceptions
Misconception: Mach 1 always equals 767 mph. Correction: The speed of sound depends on local atmospheric conditions.
Misconception: The record was established by one exceptionally fast run. Correction: The official record depended on qualifying runs in opposing directions.
Misconception: Greater engine power automatically guarantees greater speed. Correction: Drag, stability, materials, and operational constraints can limit performance.
Misconception: ThrustSSC was a conventional automobile with powerful engines. Correction: It was a specialized jet-powered record vehicle.
Misconception: A sonic boom occurs only once when an object crosses Mach 1. Correction: A supersonic object continuously generates shock waves while moving faster than sound.
