I have been doing extensive research (both on and off SS) on jumping as a method of CTB. I wanted to revive this thread and add some information I've come across. I chose this thread because it was the oldest of the two jumping "megathreads" I found and this one had more views.
I know that jumping is neither precise nor foolproof, so it's not a method with strict guidelines and procedures like others. But with a megathread instead of everyone creating their own threads that get lost over time, people can get lots of info in one place.
Don't commit suicide without reading this site! Lost All Hope has information on everything from drugs and drop hanging to suicide statistics.

This has probably been the most informative resource I've come across. It's worth a read. Here are some key takeaways:
- "jumping from 150 feet (46 metres) or higher on land, and 250 feet (76 metres) or more on water, is 95% to 98% fatal"
- "anyone jumping on land should try and land on their head, as this maximises the chances of fatal head injuries"
- "Providing the jump is from sufficient height, certainty of death is very high. Jumping from insufficient height gives a fair chance of survival, with high probability of significant, and often long term, physical injury, plus possibly brain damage."
This is an article covering the stories of survivors of jumping from the Golden Gate Bridge (GGB) and the San Francisco-Oakland Bay Bridge. The article mostly focuses on the experience people had when they jumped. An interesting excerpt: "All the survivors described this experience as tranquil and peaceful. None of them experienced life events or distant memories passing through their minds or before their eyes." This contradicts the common anecdote I read of 'people regretting their choice as soon as they jump'.
This article focuses on the injuries sustained from suicide attempts by jumping and the lethality it has. Here are some details:
- "if head and chest injuries occurred, the height fall required for 50% of patients to die was found to be 11 m" [11m is ~36ft]
- "If these injuries did not occur, the height fall required for 50% of patients to die increased to 22 m" [22m is ~72ft]
I can't find the information from the Geo Stone book that Arak mentioned above (the links aren't working for me). If anyone has access to this information, please share it here.
