we have a serious warning about the rollout of 5g, a wireless service about to go on line this wednesday. airlines are reporting major consequences with 5g airwaves interfering with airline equipment. those airline ceos say, quote, unless our major hubs are clear to fly, the vast majority of traveling and shipping public will essentially be grounded. nbc s tom costello covers all things transportation for us. tom, you ve been reporting for weeks now on this whole 5g airlines thing. this sounds very serious, right, the majority of the traveling public could be grounded? is this hyperbole? are the ceos looking to get people s attention? is this real? yes, yes and yes, if you had to really boil it down.
