I have a list ( oldish ) of around 9000 airports that I collated from various sources on the net, each with Airport Code, Name, Country, Runway Length, Elevation, Lat/Long- if anyone wants a copy email me...
Anyhow in this case, the shortest runways listed are ( apart from those with null values )
LIV - Livengood, United States - 1050ft
GLQ - Glennallen, United States - 1070ft
The longest two are
- Harare, Zimbabwe - 15500ft
UTN - Upington Municipal - 16076ft
I can't guarantee the accuracy of these but having the lat/longs has been great for waypoints in my GPS, though MS
Flight Sim Flight Plans work well as well!
