Amateur planefag here. At least 1 KC-135 and 1 E-6 in flight over the SW US.
OILER55 heading south, appears to have taken off from somewhere in the Red River valley area east of Wichita Falls, TX and Lawton, OK (is there a base out here?). Appears to have flown to Pueblo, CO, u-turned, and headed back to back to base. At some point it did a circle or two north of Amarillo, TX.
OILER57 appears to be flying the same path as OILER55 towards Pueblo, and has flown the path at least once. Currently heading NW to Pueblo.
SHADO55 took off from E Arizona (Hopi Reservation, is there a base here?) and is headed east over NM almost to the TX border, approaching Amarillo.
Looks like something's going down, anons.
