Conga lines of K35 tankers, 2 E3TF, a couple Aussie AWAC and SNOOP41 fanned out across California, Nevada and AZ.

Looks like Travis AFB, CA; Nellis AFB, NV and AZ ANG, Sky Harbor in Phoenix are the destinations.

Possibly a joint training exercise as anon has done projects at all three in past October's and had to shut down to accommodate.
