Can you decipher the pigeon-code?
The unexpected findings of a dead member of the National Pigeon Service of the Royal Air Force - a unit of 250,000 trained pigeons during the Second World War as messengers – which was found stuck inside a chimney in a home in Surrey by the owner of the house while he was renovating the fireplace, is reviving the interest in the ingenious communication technique worldwide, that had been widely used in the past.
David Martin, the man from Surrey, England, found the ‘scroll’ inside a small, red, plastic cylinder, which had been attached to a leg of the bird. Although, only the skeletal remains of the bird are visible, the container has managed to keep the message intact for more than six decades, despite being enveloped in soot and dust in equal proportion.
By strange coincidence, the message consists only of 143 characters –3 more than the length of a Twitter message: there are 27 5-letter words, arranged in 7 rows; the last two words have numbers and a back-stroke.
It has not been deciphered yet; so it is your chance to have a crack at it!
