Plane spotting

One of my sons and me enjoy going to the local airport sometimes. There is a little hut where you can stand and sit and watch the aircrafts start and land. It is best the days when the wind comes from the right direction (southwest-ish). In those cases the aircrafts always land and start from the end where the hut is situated. Need to get a suitable Fuji lens for this kind of photography so it may take some times before new images arrive here.
