Graham Spring, Christopher Sloane and Mr Sloane’s wife Karen all died when it veered off the motorway and overturned late on Saturday night. The other 40 passengers were all injured and two remained in a serious condition in intensive care yesterday.
The coach was carrying 43 people back to their homes in the Evesham area of Worcestershire from a shopping trip to northern France when it crashed near Slough, Berks.
Police were yesterday still trying to determine the cause of the crash and which driver was at the wheel, but said no other vehicle was involved.
The 57-seat coach was owned by Mr Spring’s family business. The coach, which was nine years’ old, had picked up passengers in Evesham, Badsey, Wickhamford and Pershore after setting off at 5am on Saturday
Mr Spring’s sister, Pam Spring yesterday said she had no idea why the crash had occurred.
She said Mr Sloane, a father of two who was in his late 30s, had been with the Evesham-based firm for 10 years. “He was very loyal to the company,” she added.
The Sloanes’ children, a 16-year-old girl and an eight-year-old boy, were being looked after by family members, said a friend.
Mr Spring, who also has two children, had been the mainstay of the firm since his father suffered a stroke earlier this year, Ms Spring said.
Ms Spring, who helps to run the coach company, continued: “It’s very difficult. I have lost my brother who was the rock of the business. I am just numb with shock.
The dead and 28 of the injured were taken to Wexham Park Hospital in Slough.
Chief Executive Andrew Way said all but 10 had been discharged after being treated for minor injuries.
One patient was still in intensive care and two more remained under observation. Mr Way confirmed that the five people killed in the accident had also been taken to the hospital.
Hillingdon Hospital in Uxbridge treated 12 victims of the crash, five men and seven women, but only two remained in care yesterday morning.
