Was leaving home my at about 1:00AM to workout at my 24/7 gym and saw an object ssw through trees with no leaves. It appeared to be triangular in shape with a longer row of green lights below, and shorter row of red lights in from. I live about 2 miles from Bay Saint Louis (Gulf of Mexico) and it could have been over these bodies of water. The lights were bright, possibly a little brighter than typical airplane lights. Curious that it was slowly rising, I watched as it rose above the tree level to about 45 degrees. This took about 2-3 minutes. It was rising so slowly I initially thought it was stationary. At that point it turned to a horizontal position with the red lights now in front and green on rear. It took off at a rapidly increasing speed and appeared to be at a very high altitude. It took about a minute or so for it to disappear from view–an area of approximately 90 degrees. My home is between Stennis Aerospace and Keesler Airforce Base in Biloxi/Gulfport. So I see planes often, but nothing like this. Just curious.
