From the CORGIS Dataset ProjectBy Austin Cory Bart (firstname.lastname@example.org)
This dataset is all about flights in the united states, including information about the number, length, and type of delays. The data is reported for individual months at every major airport for every carrier. Additional information is available: http://www.rita.dot.gov/bts/help/aviation/html/understanding.html
Download all of the following files.
(require "airlines.rkt") (get-reports false)
(require "airlines.rkt") ; These may be slow! (get-reports true)
Optional argument to control whether ALL or SOME of the data is returned for this function. This makes it much easier to develop and test your code, only using a large (slow) amount of data when you are ready.
