Please note that the gateway currently lists NK26 as Coles Landing 
Coles Landing is at 42.05100 / -78.98700 and is not NK26 per Airnav and FAA
This is a new airport request as Old Forge is not currently on the gateway
I don't know if it is possible to correct the FAA identifiers when adding Old Forge
I have a custom 3D airport ready to go for Old Forge NK26
