N94KS was issued to that Cessna in August 2005. What was the date of the video you were watching?
FAA records do not show you the aircraft which had a registration number in the past. And many, many reg #s are recycled.
The only aircraft currently listed with King Schools as owner is a C-172 - N81KS - on 2/13/2008.
A Google search shows King Schools awarded give away aircraft in 1994 to T.A. (AL) Marshall or Valkaria, Florida in 1994 - a Mooney Special Edition Reg N94KS
