It makes sense now, as I drove past the entrance to the track that leads to the old R101 mooring mast position I saw a UK Power Networks vehicle parked there this morning.
Yesterday I saw the Airlander passing across the end of my garden and as it disappeared over the trees towards Cardington Airfield I noticed that it pitched down in a rather aggressive manner. It wasn't until later that I realised that it had made a hard landing, but I immediately thought back to what I had seen and took the view that the nose down attitude started well before the airfield boundary.
I couldn't see any lines hanging from the Airlander but that doesn't mean there wasn't one.
The power lines run out to one or two isolated farms between Cotton End and Cardington village.
