Fearless Tower
Touchdown! Greaser!
Tower is going to be the least of your worries. You are still going to be talking to someone in CDC/CIC first. If it is a bona fide emergency and the CO does give the okay for you to land, they will clear the traffic out just like a land based airport would.The tower on a carrier isn't manned unless flight operations are going on. If a recovery is in progress, good luck feeding yourself into the pattern. If the recovery is not in progress, the flight deck will not be clear. That is a storage area and normally only cleared out for recoveries. Unless the carrier was already on alert you would arrive mostly unnoticed..
But you are correct about the deck likely being fouled if flight ops are not in progress.
I'd agree with this. Unless they rig the barricade for you, I think you are simply better ditching next to the ship than taking your chances hoping you make it on the deck safely.But in reality, by far the safest thing to do would be to ditch nearby the carrier. If it were me, I would fly overhead the carrier to get its attention and ditch ahead and slightly offset. That way the crew would be ready to help instead of potentially considering you a threat.
As far as landing on the carrier, I am willing to bet the large majority of pilots would land long and dribble off the end. That would be way worse than a controlled ditch.
