American AWACS aircraft and tankers were in danger of disaster

The full fleet of tankers, reconnaissance aircraft and early informing machines belonging to the U.S. Air Force have been grounded in fresh weeks due to 1 faulty component of the Boeing 707. It required an exchange in, for example, 24 of the 90 controlled KC-135 Stratotanker tankers, but the problem was besides addressed by the exploratory RC-135/WC-135 and key for E-3 Sentry air operations. They were the last ones to pass the check, but the number of grounded aircraft was not revealed.
