Even if this may be right the Lighthouse is about the highest point of Blackrock. This means they would have had to sink below lighthouse level. Which wouldn't have been a good idea at Blacksod either, the latter one being pretty much at Sealevel.
Even if the track might indicate that the FMS sent them to Black Rock instead of Blacksod it doesn't fully explain why they possibly collided with terrain and definitely collided with the water.
