I was doing ATC at SFO recently, and an aircraft becam white, now I figured it was unknown, and was not going to bother with it too much since there was like no traffic. But then he contacted me, and I was able to contact him, and we were in good coma till the ground. He was white all the way, I was also doing ground, and he was white there too, and again no problems… I was under the impression that white aircraft were unknown, and we had no coms, is this not the case or was this a one off glitch?
Here is the only screenshot I have if it helps anyone…
Didn’t feel like this belonged in support since nothing is “wrong” just not how I thought…
