Historical Availability
In the 1930s and 1940s, red-eye flights were not possible, as most airports did not have the equipment necessary to work at night. There are still airports that do not function after certain hours, or have curfews for noise reasons, limiting the number of airports from which red-eye flights can depart.

Famous quotes containing the words historical and/or availability:
“The proverbial notion of historical distance consists in our having lost ninety-five of every hundred original facts, so the remaining ones can be arranged however one likes.”
—Robert Musil (1880–1942)
“Since ... six weeks ago, there has been no day in which I have not had letters and visits on the subject of my nomination for the Presidency.... I say very little. I have in no instance encouraged any one to work to that end.... I have said the whole talk about me is on the score of availability. Let availability do the work then.”
—Rutherford Birchard Hayes (1822–1893)
