The main landing gear wheels are called mains for short and the steam
cleaned areas were the contact areas of the "mains" . There wasn't
debris on the runway but the contact areas were strangely a shade whiter
than the rest of it. -Unexplainable by all airport and airline personnel
that witnessed it. That doesn't normally happen when planes land on wet
(PS Are you near Yellowtail, MT? I have a cousin there.)
