Stevef,
If I remember correctly, the Shackleton crash-landed near Culloden Moor and burned out although all of the crew got out OK. I heard that the crew were picked up from the local pub/village hall where the local dance was in full swing....
Was it not at Finningley where the square of paint existed - outside the Nav School I believe. In a similar vein, the car parking spaces painted up for OC 50 Sqn and his execs at RAF Waddington were refreshed every year for AOCs, despite the Squadron not having been there for many years.
