July 28, 2009-- You might not remember how spacewalkers during the first Hubble repair mission in 1993 did the Tim Allen "hog call" from the TV comedy series "Home Improvement."

Fans of the parody film classic "Airplane" might have perked up their ears when spacewalkers Chris Cassidy and Tom Marshburn started quoting from the movie...

"Watch your vector, Victor."

"Watch, your clearance, Clarence."

"Roger, roger."

Landing is set for Friday.
