Actually this is a mistake.
I cannot remember precisely the date, because I wasn't really interested in the fact that we had passed right over the wreck of the Titanic, but I do remember the Captain, who was Commander Gobey RN sending out a 'tannoy' to the ship's company that we had just passed over the site of the Titanic, and that despite something about not being in the same location as originally thought, it was practically confirmed that a wreck lay a mile or so below HMS Hecate at that time. I remember that all of the ship's company had to do PDR duties on the bridge for 2 hours every 2 or 3 days, and I happened to be on the bridge doing the PDR thing when Titanic was found.
My guess is that someone in authority on Hecate probably let it slip about the Titanic's real location. Funny, I also remember that we were not allowed to mention the fact of the discovery, of which I completely forgot about the day after.
I remember however writing a letter to my girlfriend, mentioning the fact that we had passed over the Titanic. Can't find the letter now, as my girlfriend is now my wife of 25 years.
I swear that what I have said here is absolutely true. Somebody somewhere got their date wrong...1980 not 1977.
Regards to all, hope you found that interesting!
