I hope all are ok.

Can't make that link work, KPax.
Here's another report, from Forces Net.

The picture seems to show a landing without benefit of wheels, which might belie the RAF's "minor damage". The report also mentions "striking power lines". But no serious injuries, thankfully.

Whilst working for the company that probably owns the wires they hit, we were given a look at a programme which was available to the military showing the location of all High Voltage (11kV and above) overhead wires. I take it that it isn't in widespread use...

Those three wire strikes look like mine so that would be an 11 KV medium voltage cable assembly, the type used to feed farms etc. Not marked on any map apart from the installer's. Almost impossible to see low level against a dark background.
They believed me so that must be right.

Yup, looks like an 11kv cable. Must have been flying v low.
Also intriguing to note the strike angle - were they banking or flying along a hill when they struck the cables?

A 2013 paper covering the MoD Helicopter Safety Enhancement Programme stated,
There is currently no wire cutter kit developed for the Chinook and there are no known plans to develop one. The cost and timescale associated with introducing this capability suggest that an alternative means of protecting the aircraft against wire strike may be a better option. Assessment of a tablet based moving map capability is underway, which would have details of known wires and obstacles overlaid. The key to this type of system is considered to be an effective means of alerting the aircrew to the presence of wires without them having to spend prolonged periods “eyes-in”.
I hope the ODH found suitable mitigation to cover the wire strike risk when he signed off on the ALARP safety statement.

I seem to remember a wire detector developed for the Puma and trialled on the OCU that consisted of a ring of warning lights, they detected the current flowing through the wires, all went well flying towards wires on the tests and detecting them, however I seem to remember as they were leaving the grid cut the juice and yup you guessed right.
Funny routing to Devon 
The Chinook, from RAF Odiham in Hampshire, landed in a field near Llangynin, Carmarthenshire, after striking power lines and causing a power cut in the village.
The incident is thought to have happened during a flight to Devon.

Here you go a cheap detector
