We think the car went Mach 1 last time, and the audio has been checked by experts and they agree that's it went through Mach.
See and listen to the video here

Listen a few times and you will hear a gunshot sound at the start which people and audio experts are saying is the sound barrier being broken.
We think the car yesterday hit something on the track which caused it to roll onto its roof, causing some damage.
This probably effected its top speed.
The other videos and data collected is still being looked at.
Lastly a new car is being built and will be run early in the new year, with the aim to break 1,000 mph
