Jones, from Bedfordshire Hospitals NHS Foundation Trust, said: “Our thoughts remain with those who were injured, and everyone who has been affected by this incident.
“We are incredibly proud of the way our staff and partners responded during such an exceptionally challenging situation.”
She added she was “deeply moved” by the “incredible teamwork that shone through across our organisation and our community”.
“Staff came in at short notice, including many who were not scheduled to work, simply because they wanted to help.
“Teams across both Bedford Hospital and the Luton and Dunstable University Hospital went above and beyond to ensure patients received safe, compassionate care from the moment they arrived.”
She praised the local volunteer groups and emergency services partners “whose professionalism and coordination were vital in managing such a complex incident”.
The Cambridgeshire-based Magpas Air Ambulance said it dispatched 10 medical team members and treated 30 of the most seriously injured patients.
Daryl Brown, its chief executive, said it was prepared for “20 fatalities” and transported one patient to Oxford’s John Radcliffe Hospital.
