The plaque is directly outside the main gate to Avon Coaches! Way back then all that was just open fields! If i remember right, there was a big memorial service there years ago where relatives attended from USA.
There is quite a lot written about this crash site, ive seen pics too!
Nice reminder DAVA
IF IT HAS A HOSE THEN IM YOUR MAN
BETTER TO BURN OUT THAN FADE AWAY!
