Members of the victims families have visited the scene of the crash, it has been revealed.

Relatives and loved ones of those killed when the Hawker Hunter jet came down on the A27 were escorted by police to the site.

Eleven people are feared to have died in the disaster on Saturday afternoon as the plane was starting its display for the Shoreham Airshow.

Although no-one has been formally identified, four victims have been named by their families.

They are Matt Jones, 24, from Littlehampton; Jacob Schilt, 23, from Brighton; Matthew Grimstone, 23, from Brighton; and Maurice Abrahams, 76, from Brighton.

Sussex Police Chief Constable Giles York said some of the victims' families had opted to visit the crash site.

"It has been a devastating four or five days," he said.

"The stage that we're at now is we most likely think we've identified 11 people who have died at the scene.

"We need to give a human face to the families involved in this, and be really honest with them, saying 'we most likely think your loved one well may be in one of those vehicles at the scene'."

Speaking at the footbridge, he said the incident had been "traumatic" for everyone involved.

Describing a colleague who was one of the first on the scene, a "very experienced roads policing officer" who has been doing it for at least 17 years, he said: "In his own words, he's seen some very devastating scenes. But nothing to match what he saw on that day."

Asked what he had seen on his own visits to the crash site, Mr York said: "There is a workman's van at the scene that looks completely untouched.

"It is parked next to what looks like what looks like one of the most burnt cars I think I've ever seen in my life.

"And I think that is sometimes some of the trauma that survivors from this have to live with is: why not me, why was it them?"

He said the site was "very challenging" and part of the complexity is the number of investigating agencies, including the Department for Transport, Air Accidents Investigation Branch, the coroner, and police.

Calls were growing yesterday for the site on the A27 at the Sussex Pad junction to be kept closed for a short while longer than necessary so that members of the public can pay their respects.

However, Sussex Police wrote on Twitter: "Families of the victims have already visited. We encourage others to visit Shoreham Toll Bridge to pay their respects."
