the stealth ufo using antigravitic technoligies

i was riding i a car going west on the interstate i eaghty going west bound thruogh nebraska near the usgs place in nebreska.  a plane that looked kind of like the steulth b-2 flew over head very slowly. i first saw it when i was riding down the interstate west bound on i 80 the driver pulled over on the interstate to the shoulder and stopped. i asked him why are you stopping because on can only stop on the freeway in an emergency .he said i am stopping because there is a ufo flying see it.  the stealth like ufo flew over real slowly as if it was anti gravitic and defieing gravity. it was as big or bigger the the wing span if a seven fifty seven airline.it was painted stealth grey and had white zenon visability lights on it it had eaghteen lights on it.
We are unconvinced as to whether this is intended as a serious report.  Date may be approximate.  PD
