Here’s an interesting compilation. Of the eighteen, I’ve only been to Denver. Runway 34L/16R is 16,000′ — that’s incredibly long. When I was growing up in Edmonton, we had CFB Namao nearby and it had a 14,000′ runway. If I remember correctly it was made of concrete and was 10 feet thick to withstand potential Soviet bombardment. It was also an emergency Space Shuttle landing strip, but only for launches into polar orbit.
So, which airport on the list would you want most to fly into? Mine would definitely be Juancho E. Yrausquin Airport in Saba, the Netherlands Antilles. There’s nothing like a STOL landing and take-off in a Twin Otter. The bonus is that a flight to Saba may also require a trip into another airport on the list, Princess Juliana International Airport on St. Maarten.
