Hey! it makes no sense

If the movie is based on the book, how come the names are completely different from the actual names of crash victimes? The only one that rings true is Loft. But Ernest Borgnine was portraying Don Repo but that wasn't even the character's name in the movie. Also, I read on a Flight 401 website, the ghost stories began when a pilot on an Eastern plane was having some kind of mechanical problem and he said he thought he saw Repo's ghost on the plane assuring him things would be ok. The pilot said this all as a joke, but it was published in some flight magazine and supposedly it spiraled out of control w/reports of ghost stories. So, I don't know what the real story is, after all Eastern wouldn't admit to any of it.
