Documentary charts Mark Weir zip wire fight

Mark Weir was posthumously recognised as Cumbria's tourism personality of the year

A documentary which follows a Cumbrian businessman's attempts to build a giant zip-wire ride from the top of a mountain will air on Sunday.

Mark Weir, who was killed in a helicopter crash in March, turned the derelict Honister Slate mine in Borrowdale into a popular tourist attraction.

The documentary reveals how he spent more than two-and-half-years and thousands of pounds trying to win planning permission from the National Park Authority for the high-level zip wire.

Following his death, the 45-year-old father-of-three was posthumously recognised as the county's tourism personality of the year.

The fully-trained pilot, with decades of flying experience, died when his Gazelle aircraft crashed near the mine on 8 March.

Documentary maker Richard Macer said: "He was very much a glass half-full person and his positivity and his energy was infectious.

"Even though people had strong feelings for and against him, I would hope they would look back on him as being a force for the good.

"He brought an ancient mine back to life, provided work for local people and introduced a genuinely different sort of tourism experience for residents and visitors that isn't available anywhere else."

• Tales from the National Parks - The Lake District - will be broadcast on BBC Four at 21:00 BST on Sunday.
