In May 2006 three Catholic Priests in Ireland were warned by the authorities to stop broadcasting their services because they were interrupting with radio communications between ground control and transatlantic jets. This service, provided free by the church, was for the benefit of housebound parishioners who couldn't make it along to Mass - there are no reports of passengers on board flights actually hearing mass. According to Father Brendan Quinlan. "I knew it was a sort of a grey area, but I didn't know we were breaking the law."
So possibly if God had meant man to fly who would also have invented enough radio frequencies.
