Problem with a big lens is that the image suffers from major foreshortening .. ie everything looks closer than it is .. the pix looks a bit alarming but I suspect that the reality is a little less so ..
Having said that, the ADL 722 operation in years gone by blew the odd airport worker over (or frightened him mightily at the very least ..) if he didn't keep a wary eye on the takeoff sequences ...
Same situation ... significant use of clearway with no after takeoff obstructions to upset the effect ... depends, too, on what is the limiting calculation for the takeoff .. either way .. not at all strange to see things a bit like the URL pix.
