Isn't a glider almost always in some kind of landing?
Yes, glider is a special case.
Yes, declaring final out 5 miles straight won't make you friends.
But, in that case that one is landing and declares right-of-way.
If you are on base, you are busted, or?
Sometimes it does make sense to go in straight in, i.e. for noise abatement or if you are not in the typical tin can, but a 120 down 100 base 90 final 1,300ft/min descending flying brick - if the traffic circuit is overcrowded by 40 knots ML it may be the better chance to get down. BUT, in that special case respect is the most wanted challenge.
Last weekend I had to extend downwind two times, going far out published traffic circuit, at a crowded uncontrolled airfield, because of these straight-in-very-late-call cowboys, which was annoying, but so what - what was the other option? Yell at them on radio? I lived from the feeling to be the better one.
