The enola Gay, named by Tibbets after his mother, took off on August 6 at 2.45am. Van Kirk was navigator:
We did things the old-fashioned way, celestial navigation, telling your position by the stars. We had a dome up top of the plane to sit up in and shoot the stars with a bubble sextant. despite basic techniques Van Kirk navigated the enola Gay to its target 1,800 miles away 15 seconds later than scheduled. Fifteen seconds was damn good, thats all I can say.
