a satellite is due to slam down close to our route near Anrat with a window of 0005 UTC to 0405 UTC; WE ARE TO EXERCISE CAUTION! WTF, exercise caution?
That is one of the funniest things I think that I have ever heard in aviation. Surely it must have been somebody with their tongue in their cheek???
It is not possible to exercise caution in this type of event especially without specific and precise information.
Thanks for that little gem of intelligence!
