Few takers for technology that allows onboard telephone calls

[WASHINGTON] As the business jet climbs past 10,000 feet, Gogo Inc's onboard wireless network latches onto the Internet, and digital addicts fire up their smartphones.

Fingers fly across keypads on this demonstration flight over Manhattan to let users try an app called Text & Talk from the largest US airline Wi-Fi provider. Only there's little talk.

As US airlines navigate the new era of passengers allowed to stay connected through flights, technology may prove less powerful than American standards of etiquette. Gogo's airline customers have told the company to block phone calls when the feature is added next year.
