I'd sure like to know more about this:
Government code-breakers are working on deciphering a message that has remained a secret for 70 years.It was found on the remains of a carrier pigeon that was discovered in a chimney, in Surrey, having been there for decades.
It is thought the contents of the note, once decoded, could provide fresh information from World War II.
It was a British pigeon, presumed to have died while heading back to Bletchley Park.
Some more articles. Additional video.
ETA (11/5): Another article, and Bletchley Park news release.
I look forward to seeing the decryption.
