Can’t remember the number but there was a towline overland in the Highlands.
Tanking over land is one thing, but trailing the hoses is another as they occasionally came off on extension. Many years ago, a 101 Sqn crew were considering trailing over land in Scotland as they were running a bit late. The co-pilot was a very wealthy and much landed chap known as Bisto (Thick and rich). He checked his map and informed the Captain that it was OK to trail, as he owned that bit of Scotland!
