Once you met Dave, you never forgot him or his quirky sense of humour. “You won’t find anyone who worked harder than he did, he built an incredible business from the ground up alongside the help of his family and friends. “Bicester Motion has been a huge part of our lives, with many amazing memories and friends made along the way. “Dave was always known as the man you went to when you needed any sort of help. This is exactly what happened on Thursday evening, he saw firefighters needing assistance and helped without hesitation. “He was not a victim but a hero, he died the way he lived – helping others and putting them ahead of himself. “Although he is no longer with us, he will always be in our hearts and his legacy will continue.” A golden plaque has been installed at the entrance to the site, with a tribute reading: “Oxfordshire Fire and Rescue Service. Bicester Motion. Our thoughts and prayers go out to all of those affected by the sad loss of two firefighters and the member of the public. Love from the Bicester community.” Both firefighters worked at Oxfordshire Fire and Rescue Service and Mr Sadler was also part of the London Fire Brigade. Paul Jaggers, chairman of Bicester Rugby Union Football Club (RUFC), with which both Ms Logan and Mr Sadler had been involved, praised their commitment and enthusiasm to the sport. He said Mr Sadler, who had been involved with the club for more than 20 years and played senior men’s rugby for more than 10 years, always brought his “infectious smile and energy to every game”. Ms Logan joined Bicester Vixens in November 2021and her “determination to push herself shone” from her first session, Mr Jaggers said. “We will carry their memories in our hearts into every game, training, social and every day,” he said. Ten fire and rescue crews were called to tackle the blaze at 6.39pm last Thursday, with local residents warned to stay indoors. Explosions had been heard while locals described seeing “apocalyptic” black smoke rising above the area. A fundraiser, set up by Bicester RUFC for the Fire Fighters Charity in memory of Mr Sadler and Mr Logan had raised more than £8,000 by Monday afternoon. Fire investigators are working to establish the cause of the blaze with Thames Valley Police, which previously called it a “complex investigation which may take some time”.
