I didn't see the drone you're talking about, but I'll keep an eye out for it. I'm pretty close to the airport you mention in Carlsbad. I'll update later...

I just wandered outside for a few minutes and saw the following:

2 - civilian single engine planes
1 - Chinook - twin rotor heli - light grey probably Marines
2 - UH60's - again light grey probably Marines
1 - C-130 - again light grey probably Marines
and 2 long contrails - probably airliners

No drone at the moment but gives me something to keep an eye out for...

Maybe something out of Camp Pendleton?!?

I didn't see anything out of the ordinary either. I'm near miramar afb. I see the typical. Airliners, jets on training and also ospreys. Choppers. Radar/cop choppers over the freeway. But no drone.

Hi, I am pretty sure I saw the same thing. I am not very jet and plane savvy, but what I saw was far different than what I am used to.

It would have been somewhere between 1-2pm, I am thinking before 1:30. I was at my son's school in Escondido, off Bear Valley and east of the 15. Kids were outside doing fall party games and I looked up to see a seemingly slowish white jet. I don't mean like a private jet..it seemed more like a fighter jet, but appeared all white. It was going East and appeared kind of low. It was odd enough that I pointed it out to another mom, who was a bit surprised as well.
Texted my ex, who works for Northrop Grumman and he was a little puzzled at my description, but offered the fact that NASA uses white F-18's, so thought maybe I had pinned it down until my mom mentioned your post..
Now I am wondering if it was indeed a drone.

I've been keeping an eye on the sky today and no sign of the drone. I'll continue to look up and report back if anything interesting shows up.
