Ideal conditions for jumping?

[M_E_S]

What would you consider the ideal conditions to ensure jumping resulted in CTB? Height, location, impacting on land or water?

 

[Forveleth]

General rule of thumb is 150ft/46m onto concrete or 250ft/76m onto water for a 99% chance of death. Always good to be away from crowds where immediate medical assistance can be given. Make sure there are not fenses, nets, or a "watch" group that could possibly hinder you.

Eh, can't sleep anyway, so let's research and write up something for you:


Height
For near-certain quick death (minimal chance of survival or prolonged suffering):

• On hard ground/impact surfaces (concrete, rock, asphalt): 46 meters / 150 feet or higher. This is roughly 10-15 stories in a typical building. Below that, survival odds rise fast.
  • Around 50% lethal at ~16 meters / 50 feet (4-5 stories),
  • and almost nobody survives without major injuries above ~25 meters / 80 feet without major luck or soft landing.
• Into water: Needs more height due to surface tension acting like concrete at high speeds. 76 meters / 250 feet or higher for almost certain lethality. Golden Gate Bridge level (70 metres / 230 feet) is often used as the benchmark.
  • Even there, ~2% survive (usually with severe injuries like broken spine, shattered bones, organ rupture, very painful shit).
  • Lower bridges 30-45 meters / 100-150 feet often lead to drowning after impact rather than instant death, with many cases of relatively small initial trauma (compared to Golden Gate survivors).

Location / Surface

• Hard, solid impact (concrete, pavement, rock): Best for quick/unconscious death. Avoid grass, soil, trees, or anything that cushions since those drop lethality and increase survival with paralysis or long agony.
• Water: Deeper, colder water (like ocean or fast river) helps if the height is sufficient, but many "successful" cases still involve drowning/hypothermia after breaking limbs or spine. Shallow or slow water = higher survival risk.
• Cliffs / natural drops: Good if sheer drop with no ledges to catch you mid-fall (ledges can break momentum but often cause horrific partial survival). Bridges over water or valleys are popular because access is easy, height is reliable, and a scenic/romantic pull for some.
• Avoid anything with barriers, nets, or surveillance since many high-profile spots now have fencing, cameras, or patrols that interrupt you, which sucks.

Other factors for "ideal" (quickest, least suffering)

• Head-first entry: Maximizes immediate brain trauma over body-shattering that might leave you conscious which is very much not desired.
• No wind gusts or obstacles: Clean free-fall without spinning or hitting things on the way down.
• Night or low visibility: Less chance of intervention.
• Alone, no witnesses: Reduces rescue attempts.
• Pre-planning body position/orientation right before impact.

My conclusion: 60+ meters / 200+ feet onto hard surface or 75 meters / 250+ into deep water is the forensic sweet spot for near-instant, high-certainty end. Anything under ~ 30 meters / 100 feet risks high chance of survival with permanent damage (paralysis, amputations, brain injury, chronic pain).
Studies I found from bridge falls, building falls, and trauma centers all point in the same direction that height is king, surface second.

Jumping off a high building - Lost All Hope

Whilst jumping from height can be a very effective method of suicide (providing it is from sufficient height), it does not account for a particularly high percentage of suicides in either the US or the UK. Having said that, in Honk Kong it accounted for over half of all suicides in 20061, so...

When falling from such great heights is there a way to orient your body so you land head first? It seems most suicide jumpers land on their back or stomach and do multiple rotations while falling.

 

[Happy Cat]

Make sure you go head first so either your neck breaks or your head splatters, there's no people below you, there's a clear ground so nothing that can impale you.

You know, the only thing worse than failing in the attempt is accidently hitting someone else. But all the places I have in mind are far removed from populated areas.
Thank you everyone for your insights.
