The object appeared to be gliding at a steady speed but fast. It was dark brown and lifeless, only to be seen by the reflection of the city lights. It made made no sounds, nor did it have any signs of fuel burning from an exhaust... According to my iPhone compass app. the object appeared to be at 45* degree angle approx. 4 to 5 thousand feet above. The app. further recorded the following: 263* W ^+6 @ 4693 from the location we were @ 25*42'55"N-80*27'02"W.When we called for everyone else outside, it faded away steadily from our horizon towards the dark sky, until it blended into the nightfall as a dimming star, until we were no longer able to see it.Should you require a pic of the compass app we captured, it's available. Moreover, we each decided to draw a pic of what we saw without showing it to each other until drawn, the two drawings were very similar.To whom it may concern, this incident was very real & somewhat disturbing... Hopefully it WON'T be taken as a prank. Respectfully, two baffled individuals!((NUFORC Note: Witness elects to remain totally anonymous; provides little contact information. PD))
