Sounded like a gun shot

The parts arrived for the Caterham brakes, but I decided to leave it until I had more time.

Pottered to the shops in the Aston and found I could not park it very well. Oh well.

On the way back the car next to me at the A14/A137 junction (Wherstead) suddenly erupted. The air bags had exploded shattering the windscreen - I thought. What I missed was that they had run into the back of a car and impact had shattered the glass and triggered the airbags.

I got out and made sure they were ok but before I could talk to them both drivers were on their phones.

I was holding up the traffic and there was nowhere to park safely - so I left them to it.
