Although i think the re opening of the viewing gallery is good, you would really need to pick your times to visit as there are a lot of quiet times at bfs
Good point.
Now that the mornings are brightening there is a nice bank of movements from 05:30 to 06:15 with freighters inbound. A300, 767, 737s and Brasilia.
There are a couple of ATPs earlier than that but I don't think they're ever in sunlight.
Similarly in the evening from 19:30 to 20:45 or so, those all depart.
That's the most variety there is on a scheduled basis...
