Was Station Duty Officer one night at a not-very-secret helicopter base near Wales. A student on a resident course came to me to say he had been informed that his baby son had been rushed into hospital near London with suspected heart failure. I rang my squadron boss to inform him and asked if there was any way to fly the student down south.
As it was well after bar opening time and a social function was in full swing, the flight commander and myself were the only two pilots who hadn't had a drink. The staish was informed and he gave permission for me to leave the station. We set off in the dark and landed the student in the grounds of the hospital in a Gazelle less than ninety minutes later.
Baby had a severe hole in the heart but recovered. We were well chuffed we could help, especially as the student was an old friend of mine.
