This brings back memories. I recall that as well as their own telemetry over the actual conductor I recall they were going to create a national network by stringing up fibre optic cables between the pylons. Anyone know what happened to that

I guess that’s an “ah oops, a bit too close then”.
Over or under next time. Definitely not through.

Sort of on the theme of OH power lines - adjacent to a field we flew off for years were 4 X 300V?/400V? distribution cables on the usual wooden poles running parallel to the fence. One afternoon someone ( in the absence of any club members ) decided to fly a C/L plane - on our R/C field - to cut a long story short - pilot stumbled, let go handle, C/L plane became F/F and departed climbing towards the OH cables trailing two 30-odd foot lengths of lay-straight behind it. Said lay-straight caught on the hi-V OH power cable which stopped the fly-away, but ----- the C/L plane then wrapped it's by now anything but straight control cables several times around the power cables and shorted them out putting a couple of hundred houses onto candle power only.
There was, as expected, a bit of a hoohaa. At least we were able to say, in all honesty, nothing do with us guvnor.

Don't forget, of course, that it is illegal to fly within a 50 metre radius of the wires.

That's the one I was thinking of too. Quite a windy day if I remember correctly, I've only got a vague recollection of there being pylons at the site. I was also thinking it can't possibly have been as long as 30 years ago, but it would have been before either of my daughters were born - and my eldest will be 28 this year... Heck, how time flies!

Much of the UK's fibre-optic 'backbone' network is installed on the earth wire that runs across the peaks of the towers. A bobbin was devised which spun the FO around the earth wire.
