"Discussing probability of things is irrelevant. You seem to be suggesting that because something is so improbably it can't happen."
Probability of causes is irrelevant? HAHAHAHAHA..... mmmmpppffffffHAHAHAHA....
HAHAHaHa.... haha... ahem.... <wipes keyboard and monitor clean>
No, what I'm suggesting is that the probability of it happening is so miniscule, albeit not impossible, that in the face of the very many other FAR MORE probable explanations it is pointless spending time and resources considering it - at least until all other possible causes have been looked at and dismissed. I would consider the matter, ahead of an attack / accident by an alien spaceship, in order of probability, as something like this:
1) Structural failure, possibly due to a) design or engineering flaw; b) poor maintenance procedures; and/or c) unusual weather conditions. (85% chance)
2) Structural failure as a result of vandalism, theft or sabotage. (12% chance)
3) Damage resulting from lighting strike. (2% chance)
4) Ice falling off the wings of a passing aircraft striking the turbine. (0.7% chance)
5) Attack by a terrorist or foreign government. (0.25% chance)
6) Impact by a secret military test aircraft. (0.04999% chance)
7) Impact by a meteorite or falling space debris. (0.000000999999% chance)
8) Impact by an alien spaceship. (0.0000000000001% chance)
Yes, I know these figures are arbitrary, but they demonstrate the point I'm making, because if a qualified statistical analyst were to evaluate probabilities from available data the results would still resemble the curve produced by these numbers. Yes, an impact by an alien spaceship does indeed have a finite probability of being the cause, but it is so unlikely that any consideration of it as a viable option before the other possible causes listed above is a self-evident waste of everyone's time and resources. This is why most sensible people are skeptical of those who ignore probabilities to espouse their favourite interpretation, rather than far more realistic and probable ones.
