There's still quite a lot of airports where RVR's are measured manually.....and because there need to be constant updates it means someone positioned out near the runway.
If you look at a lot of smaller airfields (Guernsey being one I am familiar with) there is a little fibreglass 'workers hut' alongside the runway. Some poor sod of a fireman gets to sit in this for hours on end, counting lights. How's that for job satisfaction? I knew I was in the wrong job!
In trim.
