Some say all the inconvenience has less to do with the bundling of wires in the landing gear and more to do with the F.A.A. getting its wires crossed.
Aviation consultant John Nance says all of the planes did not have to be grounded at once because there was no evidence of an immediate threat. "What we have here is an outrageous overreaction or irrefutable proof that the F.A.A. is ineffective in doing their job," said Nance.
Delta, Midwest, and Alaska Air also initially canceled about a dozen flights to reexamine some of their jets. And now the concern is that other carriers could be grounded as the F.A.A. is continues its audit of all U.S. airlines.
