effesseh, I tried to post a considered reply to your thread, also querying why it had been locked. Dumb s..t that I am, I didn't realise that it had been sent from Rumours to Tech Log. A hundred lashes.
For my trouble I got a quite snotty email from Danny, basically saying that I was some kinda idiot for not looking elsewhere for your posting.
That's twice in 24 hours that I have been insulted by people in these columns. The first was some one who could not get his/her head around what I was saying in Godzone about 60 hour duty weeks. In that case I had the right of reply and the insultee probably looks a bit silly. Sarcasm I have occasionally been guilty of in these pages, insults and flippancy, not. Sorry to get off what you wanted which was input on altimetry.
Perhaps Danny will do me the courtesy of reposting my contribution here? Or has it been consigned to the ether?
