B-2 Spirit Bombers taxi, takeoff and land at Nellis Air Force Base, NV on December 3, 2018. Unit - 509th Bomb Wing, Homebase - Whiteman AFB. Film Credits: William Lewis, Nellis AFB Public Affairs. Last summer there were 8 or 10 of them took off from Whiteman AFB in Missouri  shortly after the sun went down and I assumed that WW3 had started.  I live at the point where, once they leave the base, they turn and start climbing.  Beautiful sight to see and a very distinctive sound when they pull the nose up.
