Two images from 50 years ago, both of which depict disasters.
The first (top) shows the collapsed bridge disaster at Durkar, near Wakefield, which happened on August 22, 1967.
Three men were killed, three injured, and at the time the picture was taken one was missing, after a 60ft section of a motorway bridge collapsed. Rescuers formed a human chain to move steel reinforcing bars so that a trapped man could be reached.
Two massive concrete sections, each 30ft long and 58ft wide and weighing about 250 tons, crashed into the river.
They formed part of the 250ft centre span and as they fell men leapt in all directions to escape. Scaffolding, girders and timber surrounding the bridge work was carried in a tangled mass into the river.
The men who died were: Brian Bailey, 19, labourer, of Lea Lane, Featherstone, near Pontefract; Keith Youngman, 26, carpenter, Vale Terrace, Knottingley, near Castleford, and Michael Alan Norton, 28, foreman carpenter, Ovendale Road, Wombwell, Barnsley. The injured are: Brian A. Norton, 21, labourer, of Anderson Terrace, Girnall Lane, Featherstone (no relation to Mr Michael Norton); Richard Toole, 47, ganger, of Parkside Road, Hoyland Common, near Barnsley, and Joseph Shaw, 21, of Parker Road, Horbury, Wakefield. The man still missing was Peter McHugh, 39, carpenter, of Hall Park Rise, Horsforth. Police frogmen were called to help in searching for Mr McHugh.
Our second picture (bottom) shows the aftermath of a rail accident near Thirsk, North Yorkshire in August 1967.
A man stares forlornly out over surrounding fields while just feet away are the collected bits of baggage from some of the passengers. Seven people died and 44 were injured when a London-Edinburgh express train with 300 passengers aboard hit a derailed goods train.
