Fancy a try at cryptography?

Here's an historical puzzle:

CAN YOU CRACK THE PIGEON'S CODE?
A coded message found attached to the remains of a hero D-Day carrier pigeon may never be cracked, British top codebreakers have admitted.

Hand-written on a small sheet of paper headed "Pigeon Service," the message was found in a red cylinder still attached to the bird's leg bone.

The pigeon's skeleton emerged in 1982 from the chimney of 17th-century home in Bletchingley, Surrey, when the home's current owner David Martin decided to restore the fireplace.
The code is transcribed in the article's text and what elements are known are mentioned. Have at it!

Yes, please

Thousands call for Turing apology

Alan Turning was a brilliant British mathematician and groundbreaking computer scientist. He is best known for being a code-breaker during World War II. But he was prosecuted in 1952 after admitting that he had a sexual relationship with a man. He lost his security clearance. He was 'treated' with chemical castration. Two years after the prosecution, he killed himself.

The call for an apology and posthumous pardon was begun by computer scientist John Graham-Cumming. He has also asked that Turing be knighted posthumously. I say, yes, it is about time.
