West Coast - your raw nerve is showing badly.
Yes, everyone makes cock-ups. However, with the march of technology these cock-ups should become fewer and fewer.
I presume that the Buff has GPS capability; Farnborough also has a published lat/long and identifier. I would also presume that, on a flight from the States, the GPS would, most likely, have been one of the primary nav instruments. So, either the nav programmed the GPS incorrectly or it was programmed correctly but someone chose not to believe it on arrival and opted for what they thought was Farnborough courtesy of the Mk 1 eyeball. Either way it shows a degree of unprofessionalism conducted in the full glare of publicity.
So, in the absence of a reasoned explanation from those involved this thread will now degenerate into a "Boo hoo, stop picking on us" from WC coupled with a ....Brit aircraft did this at that location...and countered by....American aircraft (x1000) did this at that location...etc etc
