    It seems at least one World War II-era carrier pigeon died in vain. Earlier this month, David Martin, a resident of Surrey, England, found parts of a decades-old pigeon skeleton when he was cleaning out his chimney. This was no ordinary pigeon. The bird had a red canister attached to its leg with a secret code inside — 27 groups of five letters each, which has completely stumped Britain’s top code breakers at Government Communications Headquarters and at the prominent Pigeon Museum at Bletchley Park. Officials are hoping that the public release of the uncrackable message might uncover the necessary code books to decipher what the sender was trying to convey. But why is this missive proving so hard to crack?
