Three people killed in a fire at the former RAF base in Oxfordshire were named by police on Thursday.

Thames Valley police said firefighters Jennie Logan, 30, and Martyn Sadler, 38, died after hearing the explosion at the business park and Bicester Motion at the former RAF base.

David Chester, 57, a public from Bicester, was also killed, the force added.

"The families are supported by specially trained family liaison officers," Thames Valley police said in a statement Friday night.

“We have begun an unexplained death investigation led by the main crime team. This is not a criminal investigation, but as the investigation continues, we will follow the evidence.

“We will continue to keep officials on site for several days to ensure the public stays safe.

"The fire and rescue departments are still on site, mitigating the fire. Once the site is safe, our investigators will be able to check at that location."

Oxford County Council said two other Oxford County Fire and Rescue Service firefighters suffered serious injuries and were in the hospital.

Tim Metcalfe, assistant commander of the Thames Valley Police Department, said: “It’s an absolute tragedy and my thoughts, as well as everyone in the Thames Valley Police Department, with family, friends and colleagues of Jennie Logan of the Oxford County Council Fire Department, Martyn Sadler of David Brigade, London, London, and Chester Public David Chester of Diest Chisester of Diest Chisester of Diest of Diest offence of d Diest of d Diest of d Diest.

Bicester Motion is home to more than 50 professional businesses focusing on classic auto restoration and engineering, and is located at the location of the former bomber station Raf Bicester.

People laid flowers on site on Friday. A pile of notes left by a family reads: “Send all our love to those who have lost their lives, and those who have not thought twice before acting to help others.

“Think about fire services, their family, friends and the wider community and all the services to help. Have a break.”

Another person said, “Thank you for your service.”

Amy Angeletta said she has moved away from community awareness. “People have lost their lives, it’s a very close community,” she said.

"It's just for tribute. The atmosphere in the area is very friendly. At times like this it feels like everyone is together."

A plaque was also placed to honor those named after the Oxfordshire Fire and Rescue Department and the Bister Movement. It reads: “Our thoughts and prayers are for all those affected by the grief of the two firefighters and the public.

Keir Starmer pays homage to the two dead firefighters. He posted on X: "Devastating news. My thoughts are with their family and friends. The courage of our firefighters is shocking. Hopefully, people in the hospital will recover quickly in full swing."

Ten firefighters and rescue workers were called to resolve the fire, which began at 6.39 p.m. Thursday and prompted responses and warnings to residents staying indoors.

The Council said the fire was under control on Friday morning. Other support equipment remains on site, including hydraulic platforms, water carriers, command units and large-capacity pumping units.

London Fire Brigade Commissioner Andy Roe said: “It was obviously a very difficult time for all of us; we lost a respected and beloved colleague who showed courage and selflessness in serving others.

“Our idea is to work with all the families, friends and colleagues that this tragedy has affected. We are doing everything we can to support Martyn’s family and colleagues.

“It has been a very challenging day for UK fire and rescue services. This event highlights the high-risk nature of the services we provide every day.”

Vikas Talwar, 40, lives near Bicester's Action and can see the fire from the corner outside his home.

He said: "There was a lot of smoke yesterday. A lot of people gathered around the corner, but a lot of smoke came out.

"There is flame on the roof, there is a large swath on the top of the roof, and there is a lot of smoke in the air. I can see it from this corner near my house."

Speaking of those who died in the fire, he said: "It's so sad. It's very heartbreaking. We sympathize with those involved.

"I could see that when they came in, the fire brigade and the ambulance team had a quick response. I saw the air ambulance in the air at night."
