What is the actual safety record of the B-52, which i subjectively consider to be the safest machine in history.
How would the B-52 match up against modern commercial airliners? (Does anyone, other than boeing, even track this stat?)
The calc would be something along the lines of;
Date-of-design -> completion, testing, commissioning, hours in flight - accidents, crashes,pilot error, time in service, fuselage age, etc...
I am subjectively of the opinion that the B-52 is the greatest aircraft ever made.

- ceejayoz 7y agohttp://www.airsafe.com/events/models/rate_mod.htm http://www.airsafe.com/events/models/rate_mod.htm indicates 79 fatal 737 incidents with about a quarter billion flights under their belt. https://www.globalsecurity.org/wmd/systems/b-52-safety.htm https://www.globalsecurity.org/wmd/systems/b-52-safety.htm indicates 76 B-52s destroyed in accidents across 7.5 million flight hours. They're not perfectly comparable sets of numbers, but the B-52s look substantially riskier on a per-hour basis.
- samstave 7y agoThank you for this! 76 machines destroyed, carrying (obstensibly) nukes.. from 7.5mm flight miles == .00001% risk of failure. Did I do the math correctly? With ZERO nuke detonations... And a flight carcass of nearly 70 years old now???
- ceejayoz 7y agoAll aviation is pretty damned safe. > With ZERO nuke detonations... Chalk this up to the design of the weapons themselves, not the B-52s. It's actually quite difficult to have an accidental nuclear detonation. > And a flight carcass of nearly 70 years old now??? Today's B-52s are largely Ships of Theseus. Not much in them is going to be original any more.
- my_first_acct 7y agoA handy website [1] notes at least a couple of B-52 nuclear incidents. In 1961, a B-52 carrying nuclear weapons broke up in mid-air over North Carolina; the bombs did not detonate [2]. In 1966, a B-52 crashed due to a mid-air collision with a refueling tanker over Spain. In this case, the non-nuclear explosives in two of the nuclear weapons detonated, scattering radioactive material [3]. So I would not say "zero nuke detonations". And your .00001% failure rate (I didn't check your math) is not meaningful unless compared to the failure rate of other aircraft. The B-52 is impressive, but not flawless.

- greedo 7y agoMost people would not refer to the incident at Palomares as a "nuke detonation," since there was no nuclear detonation. No fissile reaction etc, just conventional explosives that are part of the weapons trigger. To call it a "nuke detonation" is disingenuous.
- dralley 7y agoB52s were used for conventional bombing plenty often during their service lifetime. And they came damn close to accidentally detonating on American soil on occasion. https://en.m.wikipedia.org/wiki/1961_Goldsboro_B-52_crash#Later_analysis_of_weapons_recovery https://en.m.wikipedia.org/wiki/1961_Goldsboro_B-52_crash#La...
- xvector 7y agoIt is almost impossible to get a nuke to accidentally detonate. Has nothing to do with the B52. Let alone 1 in 76, we’re talking 1 in millions.

- dredmorbius 7y agoI'm not sure what point you're trying to make, but shifting the goalposts from airframe incidents to ordinance safety really doesn't suit this discussion. The B-52 is an interesting case of a set of exceptionally long-service individual airframes, with current planned utilisation of aircraft built in the 1960s continuing through the 2050s. The original design being from the 1950s. That said, B-52s likely have a lighter overall duty-cycle, are subject to risks not typical of most (though not all) airliners (hostile enemy fire), and yes, face consequences of incidents beyond the scope of commercial aviation, though my understanding is that live nuclear weapons haven't been carried as a routine practice since the 1968 Thule Air Base incident and the immediate discontinuation of Operation Chrome Dome: https://military.wikia.org/wiki/1968_Thule_Air_Base_B-52_crash https://military.wikia.org/wiki/1968_Thule_Air_Base_B-52_cra...
- brians 7y agoThat’s not subjective; you just made it up. For one thing, B-52s seem to have substantial safety externalities for nearby cities.
- burnte 7y ago>That’s not subjective; you just made it up. That's the definition of subjective. You're thinking objective.
- samstave 7y agoThank you. This is going to come across a subjectively offensive to people on HN, aside from the old timers, as I am such, stop trying to prove how smart you are. Listen more. Engage rather than flex your ego. Discuss rather than downvote. I almost never vote on anything, @dang may likely be able to look at my click record. I don’t click on votes too often, I engage in discussion as often as possible. (Constantly hit with “you’re posting too fast”) So don’t downvote me. Talk to me please. EDIT; cowards
- kelnos 7y agoOk, I'll bite: your original comment wasn't useful at all, and didn't push the conversation forward. Making a baseless suggestion that the B-52 is the "safest machine in history" is not useful. You presented no evidence for this claim, and used "subjective" as a weasel word to avoid responsibility for what you were saying. And then, incredibly, you make a -- reasonable -- assertion as to how you would determine a plane's safety and reliability, but then don't actually bother to try to apply that to the B-52. And then someone downthread uses something similar to your methodology (while presenting hard numbers and sources) to prove you wrong that the B-52 is the safest plane ever. So my subjective opinion is that you've provided nothing of value to this conversation, and that is why you've been downvoted. Oh, and calling people "cowards" when you don't like what they're saying or doing? If you want to invoke "old timers" on HN, you might as well at least pay attention to the site guidelines. As someone who has had an account here for 10 years (funny coincidence that you and I created our accounts within a week of each other), you should be well aware of them.
