> NTSB investigating the runway landing of a Boeing 712 without the nose gear extended at Charlotte/Douglas International airport in Charlotte, North Carolina.
It's difficult to trust a news source that can't properly identify an airframe model in an article about an airplane crash. As far as I can as a tell, Boeing has never produced a model 712, it appears what the plane in question is some variant of the 717[1] but that's only a guess as I'm not an expert in the field.
