Cultural References
Title Reference: "In Plane Sight".
This title has double meanings; one referring to the use of airplanes in the episode, and one to the very common expression "In Plain Sight". This expression is a way of saying that something is very easy to see, whether it's really big or really unique. This episode therefore makes a spoof of the expression, as the CSIs have to find something not easy to see at all. With these two references put together, you get the episode plot in which the CSIs find a body in the toilet of an airplane, and the investigation reveals highly-hidden secrets.
