UFO Sighting in Henderson, Nevada on 2016-03-28 16:30:00 - Bomber transits cylinder. cylinder was approximately 100 ft. above bomber.

I have been a sky watcher (day and night) all my life so consequently i was engaged in that activity one late afternoon on or about march 28, 2016. the atmosphere was crystal clear with intense blue skies. i was facing due north and, turning slightly to my left, i noticed a four engine bomber, emitting condensation trails, flying an east to west heading. when the plane was somewhat overhead i noticed a cylinder flying from the e.N.E. to the s.S.W. and when the bomber was directly overhead it passed under the cylinder such that they visually formed an "x". it's hard to estimate the vertical distance between plane and cylinder, but if i were the bomber pilot i'd be very worried especially if the cylinder were to appear on radar, and how could it not? from my vantage, the cylinder was about the length of the plane but about four times the diameter of the other craft. after transiting the cylinder, the plane continued west and the cylinder was lost in the sun's glare in the s.S.W.
