People just want to talk. That's their nature--even at 30,000 feet.

They have been trying to end-run the blocks on American Airlines' new Gogo Internet with wings service and make calls with Skype and other Voice on Internet Protocol services.

They've had varying degrees of success since the service took wing on Aug. 20.

Be warned that American and Aircell, the provider of the in-flight service for American and soon other airlines, don't approve. They will try to stop you.

American allows Skype IM, but not Skype or audio or video calls.

Brenda Chroniak, spokeswoman for Aircell, sent me an e-mail to explain the position of Aircell and American:

"It is against American's policy and Gogo's terms of service to use VoIP. Aircell has multiple protocols and practices in place to prevent the use of VoIP. Obviously, it is extremely difficult to stop every instance of VoIP but Aircell is monitoring and working constantly to enforce American's policy and Gogo's terms of service."

So the VoIP police are sniffing out intruders.

Chroniak said the point of the exercise is to protect the comfort of other passengers.

I can understand that. It's plenty noisy at 30,000 feet already. Some people won't want to overhear people talking on the phone.

Still, over the years there have been various schemes with in-flight phones, which probably didn't catch on with masses because of the expense.

But I've haven't had a response to my proposal of Skype and non-Skype sections on airplanes.

American, Aircell, any thoughts?
