> The “sniper” theory
> The lack of a concrete explanation for the failure led SpaceX engineers to pursue hundreds of theories. One was the possibility that an outside “sniper” had shot the rocket. This theory appealed to SpaceX founder Elon Musk, who was asleep at his home in California when the rocket exploded. Within hours of hearing about the failure, Musk gravitated toward the simple answer of a projectile being shot through the rocket.
> This is not as crazy as it sounds, and other engineers at SpaceX aside from Musk entertained the possibility, as some circumstantial evidence to support the notion of an outside actor existed.
- which sounds fairly close to "don't get caught dismissing our PHB's current crazy idea".
There's a lot, A LOT of money in play here. Technical reasons are usually the cause, but I wouldn't completely discard sabotage if there's some way they could get away with it, if only to improve procedures.
(Assuming you are referring to last night's incident, not the 2016 one.)
No, I wouldn't completely discard it. Nor would I limit sabotage scenarios to stealthy snipers. It could be anything from a suicidal pyromaniac with a hammer to a hacker messing with engine control software and prediction markets, to a nation-state actor.
Also, if your billion dollar rocket can be destroyed by a $2 bullet, maybe you need to look at hardening your design.
A sufficiently advanced technological field is one where any expert would start laughing at you for suggesting "hardening" against bullets. The denominator for rockets is always mass. Most of the difficulty is derived from not just doing a thing, but doing it in as lightweight a way possible. There are rocket stages that won't even stand up under their own weight, we have to inflate them like balloons just to move them.
In simpler terms: A bullet-hardened rocket would be about as usable as a lead balloon.
