Data from Boeing Field (King County International Airport) received today show that there are no super-noisy night-time flights in or out of that facility.
In our posts on 13 & 14 April, we reported that at Sea-Tac Airport there is a consistent pattern of very noisy aircraft, operated by FedEx, arriving & departing in the time frame, midnight to 6 a.m. The data covered the period 15 March through 5 April, which we believe is reasonably representative. The "guilty" aircraft are DC-10s & MD-11s. At our request, Boeing Field supplied the data for night-time operations there for the same time frame. Not a single DC-10 or MD-11. No planes operating during that hours that would be considered particularly noisy.
Renton has told us that they have essentially NO night-time operations, & absolutely no heavy noisy aircraft.
The mystery of the noisy flights is solved. Case closed. FedEx is responsible.
