A Real Casualty
Whatever the politicians and dramatists say, the reality for most casualty doctors and nurses is that there are not enough staff and resources to deal with growing demand. Many of those who come through the door are neither accidents nor emergencies, but the old, the depressed and those who prefer hospitals to GP surgeries.
The real-life drama runs longer - a waiting time of three or four hours is not unusual. The resulting frustration and abuse is born by the doctors and nurses.
These frontline health service troops are seen in action over 36 hours in one busy General Hospital casualty department - Whipps Cross, Leytonstone. Camera

Botham's Out!
91 Weeks in the Life of a Boy's Own Hero
On 29 May 1986 Ian Botham , swashbuckling superstar, was banned from first-class cricket. Authority declared that he had brought the game into disrepute. This is the story of what happened to England's disgraced hero during the nine-and-a-half weeks of his lost summer.
It's been said that Botham lives a frantic, unbalanced, unplanned life - that he can't endure days without sparkle. Now there was time to spend at home in Yorkshire with his wife Kath. But he couldn't be domestic for long. There was the chance to learn to fly helicopters - in Sussex. There were public appearances, parties, fishing trips - even a little cricket. Always the press was in pursuit. And
Botham found it hard to keep out of the headlines. But there was to be a happy ending straight out of the Boy's Own annual.
Tonight Ian and Kath Botham speak with unprecedented frankness about the pressures and pleasures of their lives.
'I want to die young and stay pretty,' says the hero. 'I don't want to grow up.'
