Another Shack towing snafu, Mk.3 this time at St. Mawgan early 60s.
Returning to pan from compass base and stopped right on the money.
The towmaster was unhitched before anybody thought to shove some chocks in. As the towmaster moves away the beast follows it and a quick look shows the air guage as low as it goes. A very loud scream from the cockpit alerts the guys below who stop the towmaster, grab the towing arm and re-attach with some difficulty and not a little risk to themselves.
No damage, no injuries, no witnesses and very little conversation on return to crew room.
