> Most of the "hard to decipher" identifiers become obvious if one knows the name of the airport rather than the city served...Grand Rapids, Michigan, has the Gerald R. Ford airport (GRR).
I'm quite confused on the accuracy of this article because of GRR. The article was written in 1994, but according to the GRR history page (http://www.grr.org/History.php#5), the airport did not change its name until 1999. I believe the GRR is for GRand Rapids, and question if this was actually written as is in 1994.
Edit: I see that the article is updated online. Still think that GRR is for Grand Rapids though.
Edit2: Source Found! A NTSB report froma crash in December of 1998 cites a weather reading from " Kent County International Airport (GRR)" (Source: http://www.ntsb.gov/aviationquery/brief2.aspx?ev_id=20001211...). I move that this shows that the airport code was GRR prior to being re-named Gerald R. Ford, and that GRR stands for Grand Rapids.
I would have just assumed it was Grand Rapids.
