I saw this mentioned in a nature programme I watched just recently and thought that it is the sort of information that you just could not do without, so I looked it up and found nine drawings on how to wrap a pigeon prior to dropping it from an aircraft. The method was used by the Royal Airforce. I knew it was the completely useless piece of information that you just needed to know:
