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.

Edit3: Further a US DoT doc from April 1998, lists Kent County International as GRR in Appendix D: http://onlinepubs.trb.org/onlinepubs/sr/sr255/apndx.pdf
