Claim 16:
17. A vehicle having a cabin for transporting passengers, the vehicle including:
a ventilation system comprising:
a segmented plenum disposed above the cabin and comprising a plurality of sub-plenums separated and sealed from one another by partitions;
a perforated panel attached to the segmented plenum and defining a ceiling of the cabin and having a plurality of perforations for air communication from the segmented plenum to the cabin;
ductwork comprising:
one or more upper main ducts extending along a length of the vehicle and in discrete fluid communication with each sub-plenum of the plurality of sub-plenums;
one or more lower main ducts extending along the length of the vehicle;
one or more vertical ducts that fluidly connect the one or more upper main ducts to the one or more lower main ducts; and
one or more seat return ducts,
one or more seat return ducts that fluidly communicate with the one or more lower main ducts, wherein the upper main ducts, the lower main ducts, the vertical ducts and the seat return ducts communicate with each other to convey air, descending from the segmented plenum through the perforated panel as a high volume, low turbulence blanket of air through the cabin, and back to the segmented plenum; and

an air processing unit (APU) in fluid communication with the ductwork and interposing the one or more upper main ducts and the one or more lower main ducts, the APU being operable to sterilize the air conveyed therein; and

one or more fans for circulating the air in the ventilation system and through the ductwork.
