Column (On a Windless Day), 2009 is a preparatory drawing by British-American artist Anthony McCall. It belongs to a series of studies for his ambitious, large-scale public art proposal, Projected Column, which was originally commissioned by Arts Council England for the 2012 Cultural Olympiad. The work was intended to be a monumental spiral of spinning steam rising 6 miles into the sky and visible for up to 60 miles on a clear day. Unfortunately, the proposed installation was beset by complex regulatory hurdles and was eventually abandoned due to concerns from the Civil Aviation Authority that it would interfere with aircraft.
