Bonnet flying up at speed

[JG]

Just had this e-mail from a Robin Hood owner. Any owners lurking that might now of any problem like this that the Hood's suffer from or is it just an unfortunate incident....

"Hi there,

I went to collect my Rh 2b from a very reputable garage who built the car for me however I only managed to get 10 miles down the road and the whole front end of the car flew up and crushed me into the cockpit.

The wet weather gear was on and probably acted as a brake and helped save me. I feel very lucky and thankfully no other cars were around when this happened.

All the bonnet clips were in locked in place by the garage and I never touched them especially as I was told I could not access under the hood whilst the wet weather gear was on and I was assured everything was ok.

In fact my only worry was the spongyness of my brake pedal which I called the garage about when I stopped for petrol.

The garage say they have carried out a load test on the locking clips and say that they went up to 3 tons and they did not break

Can anyone explain how this could have happened and what can be done to prevent it happening to anyone else as I am in a lot pain from my injuries and would not want anyone else to suffer.

Personally I think the problem could be down to panel strength and aerodynamics? My speed at the time was just coming up to 60 when this occured

Any help or advice would be most welcome"
