They seem to be testing jet engines on Boeing field this morning, Sunday 2/21. Very loud and disruptive up here on the east side of the hill! Started at 8:15 this morning, still continuing at 11:40. I really feel this type of noise should at least be confined to a normal week day and restricted to mid day. If you are bugged by this also, please join me in lodging a noise complaint at http://www.kingcounty.gov/transportation/kcdot/Airport/NoiseManagement.aspx. Thanks!
