Yeah, there is almost zero visual reference from the cockpit for fwd spot VERTREP. It’s sporty in good weather, not for the faint of heart!Mainly because it's incredibly dangerous and there's nowhere to go if something goes wrong. I'm sure there's been at least one mishap but I don't know of any specifically off the top of my head. When I was on the FFG, we still briefed it as a capability/possibility and still painted the forecastle for it (as required by NAVAIR) but we never once did it. We did do a HIFR once for our deployment certification but that wasn't all that bad.
I think, much like HIFR, it just isn't that necessary anymore and the benefits don't outweigh the danger involved.
