Speed Indicator for Jets

Is it possible to create a program that would indicate the speed of a jet while in 3rd person view? It would simply give the ultimate edge in dogfighting.
I know there are other scripts out there that are able to lock the speed of a jet, however they do not maintain speed during vertical loops. So, what are the chances of a program capable of indicating speed in 3p camera.. it would be much more effective than the other jet cheats

bump

i would also like thisone. if someone could make this happen it would be great

dogfight is a waste of time
i only use jets to transport
any jet whore i ran into a server....lets just say he tasted my stingers

maybe thats your opinion, but i would still love a program that shows me the jet speed in 3rd person and so would many do, i think
