2 unusual vehicles flying from east to west

Observed 2 bright lights coming out of the haze of the sky. Noticed them coming from the Superstition Mountains wilderness towards me in north east Mesa against Usery Mountian. The haze of the sky provided a cool looking effect with the crafts strong lights. Once the first craft came over me I noticed a strong sound of what appears to be turbine. I immediately noticed there was no wings which I found unusual. I mentioned to my wife that fact and she didn’t not notice. The second flew over both of us and my wife mentioned that I was indeed correct and also added why is the bottom so lit up? The entire bottom of the crafts were very brightly illuminated with warm white light.
The best vehicle description that I can relate is that both resembled the drop ship from the movie Aliens. Very similar in shape and look. Personally I feel these were both test vehicles from one of the defense contractors in the area. Definitely different in look to commercial aircraft and the way they were lit up was very strange. From the way they flew over the mountain ranges I would guess they were using military grade night vision.
