The life of Lynne Janine Braithwaite BEM, who died on August 12, was celebrated at a packed Lancaster Cremator-ium where friends and family said their farewells to a remarkable person.

They included the Deputy Chief Constable of Lancashire police force, who gave a speech outlining Lynne's involvement as a volunteer advisor on transgender issues, who toured the country speaking at various seminars and workshops – fighting for the rights of all transgender people.

The fly-past of the Vulcan bomber was in honour of the work carried out by Lynne as an engineer on the Vulcan to the Sky project – a campaign to get the Vulcan airborne again which was only achieved months before Lynne passed away.

Lynne, of Westfield Grove in Morecambe, certainly led an inspirational life.

She was born Lawrence James Braithwaite on July 1, 1934 in one of Beatrix Potter's houses at Near Sawrey in the Lake District.

She left school to join the RAF in September 1949, retiring as a Flight Sergeant on July 1 1989.

Lynne was awarded the British Empire Medal in the Queen's Honours List in 1976.

Her expertise was maintenance of Vulcan bombers. It was with this experience that she was called out of retirement as engineering consultant to the Vulcan to the Sky Trust.

In early 2008 the Vulcan bomber XH558 passed its airworthiness tests and flew once again. Lynne was very proud of this achievement and it was therfore entirely appropriate that the plane was present at her funeral.

After leaving the RAF Lynne ran her own business making silver model aircraft until 1992, when it went bust during the recession.

Not long after her transition to female in 1994 aged 60, she contacted Lancashire Constabulary asking what policies and procedures they had regarding transgender people.

Lynne had significant input advising on best practice for trans people as service users and employees in the police service.

Until July 2008 she remained an active member of Lancashire Northern Police Division's Independent Advisors Group where, over the years, she was consulted on a number of policing issues and policies. At the time of her death she was also an active member of Trans Lancs group – an advisory team for the constabulary, keeping them up to date with the legal and social issues affecting trans people.

She wrote several books including 'Diaries of a Transfemale' and 'From Brigands to V Bombers'.

The Press For Change website, which campaigns for respect and equality for all transgender people, paid tribute to her: "Lynne was a vibrant, indefatigable person who was always active and approach-ed life with the enthusiasm of someone decades younger. She will be greatly missed."

Lynne, who passed away suddenly but peacefully in Royal Lancaster Infirmary, is survived by her children Karen, Vicky and Mark, and grand-daughter Emma.

The commital service was led by Rev Canon Brian Pithers, chair of the Morecambe and Lancaster Royal Air Forces Association (RAFA) where for two years Lynne was secretary.
