In the early 1960s I was travelling along the M4 late at night with my Uncle when we pulled over in amazement along with dozens of cars. Everyone got out and was staring into the sky. There were three pairs of headlights up there, completely stationary and beaming down onto the motorway with a roaring sound in the sky. Then they zoomed away.
Next year the successful launch of the Harrier Jump Jet (produced in Bristol) was announced.
