^Mitchell, Robert (2001-11-19). "The Return of MiG Alley?". combatsim.com. Retrieved 2013-01-06. Bob Mitchell: What has prompted you to release the source code for MiG Alley and Battle of Britain? Dave Whiteside: Because we are no longer doing flight sims [after Empire took us over at the end of 2001], and we would not be able to publish any patches that were required [no money was allocated to this], rather than let MiG die and all the code sit doing nothing it was considered a good idea, a swan song, if you like, for Rowan [after 13 years in the flight sim market].
