Hmm. I've noticed quite a few FR's do this "extreme" line up technique at STN.... and I've seen some come
very close to doing exactly the same as the EMA aircraft whilst lining up on 23 at STN from "S" (the 45° lead on). Now, I'm all for not using up runway (runway behind you being one of the three most useless things in aviation) but is it really necessary on a 3000m runway i.e. STN and EMA? Not to mention the stresses on the main gear and tyre scrubbing.
Common sense
