Since you are an expert on nothing and was not on the flight you dont know what happened.
We overflew Cuba and the Pilot came on and said no photography while over Cuba.
Plain and simple.
Expert on nothing? Maybe so, my friend, and there are actually quite a few things I know nothing about, such as dumping lavs. As an A320 Captain who regularly flies the Caribbean, however, I do know a teeny bit about this subject.
As I stated in an earlier post, if you overflew Cuba on a TPA-CUN flight it was part of a weather deviation. It was not part of the filed flight plan. No announcement would have been REQUIRED.
The photography rule is an arcane relic from years ago. It is largely unenforced, and I can guarantee that there would be no real consequences for a passenger who violated it. The most that would happen is a request from an F/A to cease and desist, and even that is a stretch. Fact is, there is nothing significant to photograph on either of the two corridors we fly over Cuba.
Your previous b.s. post about how failure to enforce this rule could cause US Airways to lose Cuban overfly authority shows how ignorant you are. These flights are a cash cow for the Cubans, and a cutoff of any US airline would jeopardize Cubana's rights to overfly the US while enroute to Toronto and Montreal.
You seem to think we are still operating like it is the height of the cold war. In your frantic internet searching did you happen upon the "rule" that each flight will include its Cuban overfly permit number in its initial report to Havana Center? (Sounds serious!) If you did, you might be surprised to learn that no one does so, and Havana never requests it. The only exception to this would be an inexperienced crew that is being a bit overzealous. This may apply to your NWA crew - they are not big players in the Caribbean. (Oh, sorry Lavman, there are no Cuban overfly permits on flights from the US to Cancun! Hope you didn't fall for it, expert that you are).
You couldn't possibly know that Havana Center, once unpredictable and difficult to deal with, is now easygoing and extremely accommodating. They have no interest in playing gotcha, and would probably get a good laugh out of your ridiculous, self-important posts.
