Um the webbing did catch her it was the fact that the webbing caught her neck and snapped it that she died. Also, it has not been proven that Spidey's webbing is "as thick as a pencil and could hold a Boeing 747 Jumbo Jet," only in the new movies has this been referenced but not displayed by Spider-Man himself.
