The statement that 'no other skyscraper in history has ever collapsed in on itself until 9/11' was left by a commenter on this website in regard to the post, 'Proof Gov Wrong About Collapse of WTC Building 7?' – Ben Swann gets it wrong. Such statements reference the global collapse of World Trade Center building 7, also known as the Solomon building, on September 11, 2001. There are at least a few other variations of this statement, such as 'no steel framed building has ever collapsed due to fire'.
Ben Swann again repeats this claim in a video he released today, Reality Check: Proof, WTC Building 7 Did Not Fall Down The Way Gov. Agency Claims.
