3 craft seen in day light, very low altitude and as clear in detail and color as a car on the road.

The 3 ships my wife and I saw were disc shaped and slightly concave on the bottom side. On the top side there was a definite "cabin", with round port holes around the outer edge.  There was a "pole" (knob) at the center bottom. The ships were glowing from within and were an all over color like that of a bluish floresent lamp.  The sighting took place in late day light and the crafts were flying in a canyon, so we could see the hills behind them, so the altitude could be gauged some what. My guess would be they were flying at less than 200 feet altitude.
All 3 ships looked as though they were sailing on a slightly wavey sea and were gracefull in flight, with out a whisper of sound. They were moving very slowly, at a rate of 10 to 15 miles per hour.  Following each other, they each one very briefly paused, just slightly west of our position, nearly overhead.  When they took off, they traveled from east to west, at  approximately  a 45 deg. angle from the horizon, gaining altitude at an amazing rate of speed.  From our view point, they appeared to be 30' to 40' feet in diameter and when they took off, they diminished to a speck in a forth of a second or less.
Witness indicates that the date of the incident is approximate.  PD
