Anybody else hearing this?….
Hearing this rumble that sounds like a jet taking off but it only last for about 5 seconds and then stops and I’ve heard it about 6 times out here.
That note came from a Claycordian in the area of Bailey Rd. & Concord Blvd. in Concord.
UPDATE: We’re getting more reports from people off Kirker Pass, Bailey Rd., further down Concord Blvd., and a few more from N. Concord (all near the Naval Weapons Station). One other report came in from near Buchanan Field airport in Concord.
UPDATE, 8:19pm: This same thing happened in July of 2013 and also in September of 2013. At the time, nobody could say where it was coming from. Some suspected the noise was coming from the Tesoro Refinery in N. Concord, but they never were able to confirm the noise was coming from their property.
