Today I went to the the “Founders Plaza“, which is an observation point for the DWF airport. It has recently been reopened and is pretty nice. There are picnic tables, nice grass, shade, so you can spend hours watching airplanes. They even have telescopes, which are free to use, and a loudspeaker that broadcasts control tower communications (live).
This google map shows the location of the Founders Plaza (marked A) relative to the runways.
I was there for about 1 1/2 hour. Most of the airplanes landing were from American Airlines. But I was also lucky to see AN-124 from Russia (one of the 10 owned by Volga-Dniepr airlines) and a British Airways Boeing 777.
Right after the Russian AN-124 landed, one of the landing AA planes which was already almost above the landing strip, had to abort landing and take off again. It was weird to see it suddenly accelerate and retract the landing gear. Maybe the Russian plane was too slow and had not left the runway yet (I am guessing, I should have been listening to the control tower communications.)
UPDATE: Recently, I have been at the observation point again. This time a bit late, just before sunset. The wind was from the north, so the planes were taking off in front of the observation point. I had a tele lens this time (300mm with 1.4 converter, instead of 50mm). It was a bit too dark to take good photos.
