The closest explanation to what we felt was the sonic boom, but can find no reports of that over Nottinghamshire that day. Mystery persists!!


My bet is that you experienced a Dry Microburst downward draught airflow. If there were high altitude storms in the area then micro bursts can be formed at quite a distance from the actual storm, if a dry burst then there would be no rain, lightening or sound associated with it just downward pressure and then lateral force when hitting the surface.

Microburst is intersting suggestion! However, I would have expected to see that reflected in movement of the bushes next to the road, and I do to see that in the video. An exploding tire is the strongest hypothesis up to now.

Ok everyone, and specially Ken… stop it. You can confess now pantsdown

We’re grown men and know what this is all about… Let’s be sincere. We all use this technique from time to time when we’re driving in a quiet car. innocent

You need to decompress the digestive system filled with this haggis and steak pie with you had with your soda, and you’re scared it will be loud. And as you don’t want to scare your copilot, you suddenly talk out loud simultaneously to the discharge, and move the steering wheel to shake the car and make more confusion. drive smirk2

But stopping on the hard shoulder and quickly open the door – to ventilate just in case – is a master move. Ken: it was perfectly executed. Congratulations. notworthy

Ken reports it as a downward thrust a tire would be a one side rocking, the lateral air flow to reach the bushes would occur seconds after the initial event the video has moved forward from that position so would not necessarily been seen.

Everyone loves a Morgan. Even me, unless it's broken again.
