PIGEON MESSAGE UPDATE

Released : Dec 17, 2012
GCHQ and the Bletchley Park Trust have followed with interest media reporting on possible solutions to the encoded message found on a dead pigeon in Bletchingley, Surrey.
Hundreds of these proposed solutions have been carefully examined by the expert cryptanalysts at GCHQ. So far none have proved credible.
 
It remains the case that without access to the original code books, details of any additional encryption, or any context around the message, it will be impossible to decode. Similarly it means that any proposed solutions sent to GCHQ or the Bletchley Park Trust will, without such material, be impossible to prove correct.​
