Opponents of allowing cellphone calls on planes gain powerful ally

The Global Business Travel Association, a trade group for the world's business travelers, submitted its opposition last week to a plan by the Federal Communications Commission to lift a ban on voice calls on planes. The group, which represents about 6,000 travel managers, called onboard calls "detrimental to business travelers." The association even quoted folk singer Pete Seeger, who borrowed heavily from the book of Ecclesiastes when he wrote "there is a time to keep silence and a time to speak."
