will reveal the Google Satellite image of Teeside Airport and still show the 3 original MSG runways, as well as the then OM (St Georges Hotel now, as you say). Danny covered the incident some time back, but looking at the layout I'd hazard that the TO runway was the one marked 28? (strangely still not obliterated and replaced with a cross).
If that were so he didn't have that much distance to cover in a RH arc until hitting the Mess. As the Tech Site & ATC was then further East, and the modern terminal not even dreamed of, he could have had a pretty clear run until his own room loomed into view.
RIP.
