어서 지나가다

pass by or pass through

An "-아서/-어서" clause supplying the route or the cause, plus 지나가다 "go past". Physical routes: it went through Libya, passing right through Mongolia, if you pass in front of the special camera. It also covers time slipping by unused — it's a waste to just let it flow past, sixty hours have already failed and gone. And it names a passer-by: with nothing to film I'd have to ask someone walking past.
