White object like cloud, would phase in and out to the color of the sky middle of the day, somewhat triangular or stealth shaped,Traveling west of Wichita on 54 highway, around noon, saw what first appeared to be a small cloud low on the horizon, only cloud in The sky. First noticed it somewhere between Garden Plain and Cheney to the North still to the east of Kingman. While driving I noticed it would fade in and out between white like a cloud to the background of blue sky, slowly pulsing. I thought maybe birds since somewhat triangular in shape as it would fade in and out moving very slow seemed to more hover. It did this maybe 10-12 times. Didn't have much definition but when it was fully white looked similar to shape of the Stealth. Finally lost sight around K-17 that runs N-S North of Cheney Reservoir. McConnell AFB is in Wichita so are several plane manufacturers so not sure this could be some type of military experiment.
