These photos are from the first Harrier landing at Pebble Mill in the summer of 1979. This one was a Fleet Air Arm Harrier as you can see from the logo on the tail. Bob Allison took these from the balcony of Pebble Mill on the 8th Floor.
Harrier jet lands at Pebble Mill, as part of Pebble Mill at One. Keith Brook (aka Scouse) is on camera, and I think Philip Thickett is cable bashing.
Pebble Mill at One researcher Wendy Leavesley (I think), pretending to be a camera operator, down by the brook in the grounds of Pebble Mill. The photo dates from the early 1980s.
