Typical newspaper article. They were probably 3000' but to justify the story, this became 750 feet. As mentioned before, how does the Journalist know their distance from the reactor? Or even what altimeter setting the pilot had set?
Now some poor pilot will be facing questioning by the CAA becasue of some journalist decides to possibly falsify this crap story.
I would also quite like to know how a 1Kg bag of sugar (couldn't find the 7Kg bags in Safeway

) could equate to 7Kg of semtex? Surely a 1Kg bag of sugar = 1Kg of Semtex? Or are they saying that 7Kg of Semtex has the explosive capacity of 1Kg of sugar? Seems like they don't even know what they're on about...
