In a timely relation to Billy's post here about just who is editing wikipedia, comes this item about someone at Air New Zealand editing Wikipedia's account of the Erebus disaster.
This is interesting and bears further discussion, but its late, so I will examine it in a bit more depth tomorrow.
In the meantime, for those who have seen Die Hard 4.0, here is what actually happens when a hovering aircraft loses it's vertical thrust component, (i.e. the bit holding it up) thanks to the miracle of youtube.
As usual for youtube, ignore the comments. After a rough browse of the numbers, less than 1% actually know what they are talking about. Seriously. The ignorance is that rampant.
And the pilot survived if you're wondering, although he did sustain a broken ankle when he landed on his now semi submerged aircraft.
