"the pilots invited a female tour guide up to the cockpit (although it is widely assumed that the woman was Captain Daugherty’s fiancée Yvette Murray, who was also on the plane that day, this was actually not the case). "

"On top of all this, the pilots engaged in an off-topic conversation with a flight attendant (probably the captain’s fiancée)"

So what was it? Fiancee or not fiancee? Thats the question....
