Of course, a contact course because the air pushes it up only by milometres but that doesnt mean its not contactical upthrust from your good member Paul Jennings
No, upthrust would not be considered a non-contact force. It would be considered a contact force. It is making contact with an updraft of air.

Soccer/football is the most watched contact sport.
Upthrust, I don't understand what you mean...
No it is not. But then again, it is. Depends on what your definition of "contact sport" is. In most cases, ping pong is not a contact sport for it contains no actual physical contact between the players as you would see in hockey or football (which are full contact, or collision, sports). According to another definition, ping pong, in a way, is a contact sports because there is physical contact between the player and the ball (when you go to serve the ball, you are holding it. This is considered contact between player and object).
You can lose you firmly fixed teeth in a contact sport
