BOAC: thanks, 23 wasn't all that helpful to me, as it got me to Mr Leyden. Perhaps my brain was looking for an acft computer issue and so I read that into the article. 22 got me only a redirect and no site to read ... no probs, usual internet glitches. Subsequent explanation has been most appreciated.
(I had to run maintenance operations part of a lifetime ago ... having no/bad info to work with is a very unsettling happening)
