Good interview
I enjoyed this, where the interviewer has technical knowledge of the item, and assumes a good level of intelligence on behalf of the reader. As a result honest and open answers are obtained, and kudos to Mr Ottens for those. Respecting his decision not to comment is welcome too.
The BBC (inter-alia) would do well to read and heed this - too often their science/technical articles are written by someone who clearly has no idea about science or technology and I end up feeling more stupid at the end that I did at the beginning. I know that the audience is different, El-Reg attracts a teccy-type of reader, but there is no excuse for general publications to assume all of their readers have no knowledge at all. Bring back Horizon as it was in the 1970s I say, this is the kind of excellent thing they'd do, with no celebrity interviewer/voiceover and no computer graphics, maybe just a diagram to show how the heads worked, or the gearing on differing spool sizes etc..
