50 years ago, in July 1965, it was not Plane Stupid disrupting the flights at London Airport, but Ronnie Biggs.
At 2 am on the morning of 14 July 1965, six days after his escape, fifty police officers swooped on a DC-7 cargo plane at London Airport that was bound later that day for Amsterdam. They had a tip off that Biggs was hidden in one of the crates.
After an hour, the search was called off. This was another embarrassment for the police who on 9 July 1965 had raided Winterfold House in Cranleigh Surrey, then the home of Prince Carol of Rumania. The house and grounds were searched by over 150 police officers looking for Biggs.
The police sealed off four square miles of woods, grassland and lanes around the mansion. Twenty radio cars kept the police squads in touch. The following day, 10 July, the police raided the Upton House Estate, which Prince Carol rented from Poole Council. The police said at the time that they were following more tips that Biggs had been seen, but nobody really knows why Prince Carol was linked to him.
