Unconfirmed, but from a friend in the warbirds world I've always found to be reliable.
A Hurricane crashed onto the Sussex downs on open land south of Lancing College at about 3.15 pm.
The pilot didn't survive.
The crash site could not be seen from the airfield, although a large plume of smoke could.
I don't think it would be appropriate to post the name I was given at this stage, for obvious reasons.
Very sad.
