The flight, of course, follows the Great Circle route, which surprisingly (to me!) comes nowhere the Titanic's grave (about 41o43'30"N, 49o43'50"W). A plot of the Titanic's route (no idea how accurate) shows the route going south, which looks like a long way round. I suppose British Airways don't have to worry about permanent ice around Greenland - I'm amazed there are icebergs at 41 degrees north in April - or the fact that the Great Circle path spends a lot of it's distance, er, over land :-) Are there considerations of ocean current too? If you're a couple of inches from the plane window at 35,000 feet, a 1mm piece of dirt on the window obscures a Titanic's length of ocean. A.

Titanic's last position report gave her location as: 41d 46m N 50d 14m W Robert Ballard (after many years of secrecy) gives Titanic's resting place as (all 12460 feet down): Bow section 41 43 57 N 49 56 49 W Stern section 41 43 35 N 49 56 54 W Boilers 41 43 32 N 49 56 49 W None of these positions was specified with a datum so it's not clear just how helpful they are.
