As an aside, I thought the article was incredibly poorly written. The first paragraph states Dan 'plummeted to his death from 2500' then later on in the article it says 3000'. Not only that, the main article stated he was 25 years old but his picture caption states 35.
I doubt it was a high as 2,500' if he was jumping static-line. UK training jumps done from 1,000, ISTR. Talk of operational static-line jumps at 650'.
