This is from the UK last week.
I've seen the exact same thing.... 15 years ago... without the "Mother Ship " though.
It was a series of white dots that were extreamly bright, and very high. They came out of the North, traveled to directly over my head, and did a 90 degree turn,and headed out due West, over the horizon.
There were 6 of them over a 10 minute period. 3 other guys on the jobsite stood and watched them with me.
If any one knows the OC, it was a large area being graded out where "Camp James" now stands.... right next to the Wild Rivers water park.
Right after that all went down, I heard a jet engine whine..... and this came over our heads...

Its a TR-1, a supped up U2.
It circled, and landed at the El Toro Marine Base, right next door to where we were.
I called the Info center for the base, the OC Register newspaper, and my local turbo geeks who monitior the transmissions coming and going from the base..... nothin.
Theres still about a thousand unanswred questions from that day... The two biggest are WTF were those things, and the landing of the TR-1.
The El Toro Marine Base was equipped to handle F-18's, and C-130's only.
You need all kinds of crap to recover and launch a TR-1.
Was it out of fuel from chasing these things, and needed to land , pronto?
About a month after all this went down, a C-5 Galaxy landed, stayed a few days, and left. Was the TR-1 inside?
Theres weird shit goin on, and thats fo' sho.
