Thanks for the info Spheroid,
I am west of Dorchester by 6 miles, near to Cerne Abbas, but one valley over. Had confirmation from my original post that it was 6 Hawks for the Yeovilton Air Day, which i will be eating ice creams at.
Any one whos night flying and follows the River Frome Valley then watch out for a balcony wave nearby the church!!!
best regards to all in the forces.
Coley.
