Hi,
On 6/28/2012, 12:15pm I entered my home airport code (4B8) in the airport tracker. What I got was:
“Unknown or Invalid Airport Code”
I noticed this with many airports that begins with a number. Was there a software update that no longer recognizes these coded airports??

Works for me. Wish I could be more helpful.
Thanks! I logged out and back in again and it is working. Should have done that before posting 
Amazing flight from your airfield
Made it from RPMI (Malaysia) to 4B8 in 19 Minutes, in a 172
We had an issue overnight with non-ICAO airports, it should be resolved now.
It is, Thank you sir! 
Ha! Yeah, I’ve seen this before. He probably picked up an IFR, or flight following at the IGN (Kingston, NY) VOR and the 3 letter ID was the same as the local international airport ID
