In the true ephemeral nature of the net, Dr Dougal Watson has now encapsulated all his files in downloadable pdf format at this URL:
http://www.ozemail.com.au/~dxw/avmedpub.html AVMED Articles
http://www.ozemail.com.au/~dxw/avmed.html his home page
Some of the smaller acrobat files will open online and be browsable. Reason I mention it is that the URL for the "pitch-up illusion" is now defunct.

http://www.pprune.org/ubb/NonCGI/For.../009550-9.html This thread is now closed and the URL's cannot be corrected.
The "false climb illusion article does readily open online and this is the URL:
http://www.ozemail.com.au/%7Eaupa/PDF_files/DNT.pdf
(i.e. also accessible quite clearly as a link from that first URL above)
