Beachy head has places that don't slope. There is a point between the 2 lighthouses that is a popular spot.
Beachy head is of my 2 preferred methods. If jumping I will take some benzos, a few vodkas and blindfold myself before leaping to help subdue survival instinct.
I've been looking at that. I can't see any ledges in any pf the photos people have uploaded to google maps and an image search includes images where the cliffs were much more rocky in years past, showing that erosion has resulted in the increasing areas with a sheer drop, so perhaps some of the ledges are no there now. By the stripy lighthouse there is one area which seems like a straight drop, right on the point, but then even falling on the sloping bits either side are still drops much higher than the considered height for almost certain death, I'd say the deciding factor to be more if the sloping ground is still solid enough, rather than the reduction in height.
But even a bit further along towards the other lighthouse the drop must still be enough, it only looks like 20m lower so still over 100m.
I've been searching around for other high points, and as I have been looking people have jumped and died from much less. A woman jumped from Clifton Observatory in Bristol, which is just a small building. there are some of the highest cliffs in the country on Devon and Cornwall with less of a chance of anyone stopping someone from jumping, but they aren't sheer drops, at least not right the way down, though people have still managed to do it from those places, one man was even seen crouching and then just leaning forward from what looks like a straight drop and he died, but is doesn't look very high to guarantee death.
I think I'm more likely to jump sober than drunk or on tablets. Each night when I have a drink I seem to lose any urge to go, it is during the day when I am able to consider all my problems and how bad they will be in another 2 week that I find myself cutting off all my emotion and feeling like I could just go and get it done with. Mind you even poor weather would put me off when I'm at the edge, I'd think I can't do it today, it's too cold and windy, I'll freeze down there. It doesn't always sink in that that is something that doesn't matter.
Beachy head is a 5 hour drive for me. Too far and expensive to go and come back. It'll have to be a fairly decent day. Part of me has even thought doing it on a big tide, and when it is just 3 hours til high tide, so if I an alive but injured the sea will finish me off before any rescue attempt could be made.
Apparently even places like the Clifton Suspension bridge in Bristol has a high success rate. It's just harder to jump now because of the higher fencing they've put but people are still managing it. People would just need to be aware of the story of the woman who jumped and her large bell dress acted like a parachute and slowed her fall, dropping her almost sitting down in the soft mud at the side of the river.
