What will your pilots do, just as a for instance, if ... say a lone Cessna asks tower for his ground speed ... and then a bit later a navy F-18 pilot also asks tower for his ground speed ?
specially if the F-18 pilot is making sure that every bug smasher from Mount Whitney to the Mojave knows what true speed is.
I've read and re-read that story so many times, each reading results in a fresh batch of goosebumps. I'd love to read the book (Sled Driver, I think?), but it is over $500 on Amazon. I wish they either ordered another print OR published as an ebook.
