A 56-year-old man remains in a critical condition and another is seriously injured after a collision involving a lorry and four military trucks in Lincolnshire.
The crash near Boston happened just before midday on Thursday, May 19.
The four drivers of the trucks were initially trapped in the vehicles on the A17 near Swineshead Bridge and the road was closed while emergency services, including 32 firefighters, dealt with the incident.
Three men were airlifted to hospital – two to the Queens Medical Centre, in Nottingham, and one to Addenbrookes, in Cambridge – and a woman was taken to QMC by ambulance.
Police confirmed on Friday, May 20 that a 56-year-old man remains critical in QMC and a 44-year-old man continues to be treated in Addenbrookes for serious injuries.
Both men were drivers of the MOD vehicles and are from the South Yorkshire area.
The driver of the articulated lorry, a 23 year-old man, remains in hospital.
Police say one of the remaining MOD drivers did not require hospital treatment and the other was treated for less serious injuries.
