Easy solution to CV hiding: add the ability for all players (rookies, nites and bish) to see who is currently controlling each team's CVs. By displaying the names, everyone will know who is controlling the hidden CV. I'm sure the radio and message boards will discourage that player from doing that again.
I play for the bish, but I would much prefer to use and loose a CV than hide it. Problem is you can't always get it away from the person (capt. dweeber) who's controlling it.
That said, please not more magical radar, sonar, satillite views, GPS navigation, laser guidance systems, laser range finders......
If someone hide a CV, send up a couple 234's to find it..without bombs its a great recon plane.
