Well, this site is a web-formatted version of DAFIF (RIP ;-)). DAFIF
has no complete list of airfields, not even of those with ICAO codes.
Less than 10,000 of them.

I already came across several incomplete lists. But thank you anyway,
looks nice.

Just curious, why limit yourself to airports with ICAO codes? In the
U.S. that's probably only about 1/2 the airports.

Well, I need some kind of index. Handling them by 'name,state,country'
is a bit tedious - and maybe not unique. So why not take the ICAO code?
Idea was to find a workaround for airfields without ICAO code. I didn't
expect their number so large. Thank you for the advise.
