description=Wherever you want to go today, the Cessna Caravan can get you there. First introduced by Cessna in 1985, the Caravan was designed to land nearly anywhere, on land or water. Undoubtedly, it has lived up to its creators' intentions. Whether supplies need to be brought to a flooded village in the mountains of Peru, an injured person needs to be flown out from a remote lake in Alaska, or an archaeologist wants access to a tiny site in the African desert, the Caravan has what's needed to do the job.
