That's only true when you're talking about firing straight up. At lower angles a bullet can go in an arc and still have a significant amount of lateral velocity when I comes down because gravity only acts in the vertical direction. It will still be slowed down somewhat by air resistance but that's not necessarily enough to make it non-lethal (if bullets couldn't overcome air resistance then guns would be useless in an atmosphere).

You seem to have forgotten the Atlas V and Delta IV.

Atlas V had a "partial failure" where the second stage cut off 4 seconds early in a 900 second burn; but even the customer (NRO) still called it a success. If Falcon 9's aborted secondary payload doesn't count as a failure then I can hardly see how Atlas' slightly lower orbit does, which means it's at 54 successful launches and counting.

Delta IV-M on the other hand has never had even a partial failure, 21 launches going. The Delta IV-H had one partial failure but that's a rather different animal.

Also neither vehicle has ever had a total failure.

Well yea, recruiting is the entire reason for the existence of AA, nobody disputes that. The GPP however was insinuating that the only reason (or at least one of the main reasons) war FPS games in general exist is because the DoD funds them. That's silly, franchises like CoD and BF make money hand over fist, there's no reason for the DoD to bribe someone to make them.

Comment Re: Just because... (Score 1) 333

I'm not sure how useful that would be in practice though. The only "aborts" after t-0 that I've ever heard of were due to either A) the rocket blew up or B) loss of control of the rocket resulted in it straying off course and then being blown up by range safety. Either scenarios preclude any attempt at landing (you either have no rocket or no control of the rocket). Is there any other reason a mission would be aborted post-launch? Even with human cargo I'd think you'd jettison the capsule if things were bad enough that you had to abort.

However, Boeing has pulled the Delta IV from the market, so there will be a limited number of these launched in the future.

Got a citation on that? Last I heard there was no definitive plan to end the Delta IV program, in fact it would be insane considering Atlas' precarious engine situation.

You clearly didn't even read what he posted because it specifically mentions the eruption of Mt. Pinatubo. It was the largest eruption the world has seen since 1912, yet it would take 700 of those eruptions a year to even match human annual output of CO2, much less dwarf it.
