In my latest game (PTW 1.27f UK version) my helicoper did a recon mission. The next turn the city in which the helicopter was based in culture flipped... BUT the LOS given by the recon mission was still there, and has there remained ever since. I believe there is a bug concerning losing a plane (possably only a heli to culture flip, but it may be universal) after recon missions. I have had this problem before but never connected it with losing the aircraft. This, although it would be very hard to use as an exploit, is quite an annoying bug...

Another bug/feature - radar towers. You cannot land paras on them, nor can you land troops (apart from marines) on the square they occupy, nor can you helidrop people in. Is this intentional?

And while I'm on the subject - paras should be able to attack from the paradrop - perhaps with half attack rating, to simulate them firing they're guns as they come down.
