Continuing in her bid to destroy Barbara Walters’ credibility and ABC’s program “The View,” Rosie O’Donnell’s factually deficient and irresponsible comments are rising in frequency and outrageousness.

Rosie recently gave viewers a pseudo-science lecture on the events of 9/11.

“I do believe that it’s the first time in history that fire has ever melted steel,” O’Donnell confidently affirmed. “I do believe that it defies physics that World Trade Center tower 7 — building 7, which collapsed in on itself — it is impossible for a building to fall the way it fell without explosives being involved. World Trade Center 7. World Trade [Center] 1 and 2 got hit by planes — 7, miraculously, the first time in history, steel was melted by fire. It is physically impossible.”

Rosie’s “scientific” statements prompted a response along the following lines from Popular Mechanics magazine:

• Steel was weakened, not “melted.” The crashes destroyed support columns and ignited raging fires that weakened the steel structures so that the towers could no longer support their own weight. Building 7, which had fuel tanks located throughout including two 6,000-gal. tanks in the basement, collapsed because fires weakened its steel structure. Steel melts at about 2,750 degrees Fahrenheit, but it loses strength at temperatures as low as 400 F. When temperatures break 1,000 degrees Fahrenheit, steel loses nearly 50 percent of its strength.

• The North and South Towers weren’t knocked down as a result of being “hit by planes.” In fact, both towers remained standing for more than half an hour after the planes hit.

• Tower 7 wasn’t hit by a plane but was severely damaged due to debris from the collapse of the North Tower. In early photographs of building 7, smoke and debris obscured the pictures so that the first reports from FEMA did not take into account the extent of damage due to the debris from the collapsing 110 floor North Tower. After additional studies, the National Institute of Standards and Technology (NIST) indicated that the debris from the North Tower hit building 7 with the force of a volcanic eruption. Almost a quarter of the building was carved away from floors 11 and higher. The NIST has found no evidence of a blast or controlled demolition.

Lack of evidence never seems to stop Rosie. She also spoke out on the British sailors who are being held hostage by Iran.

“There were 15 British sailors and Marines who apparently went into Iranian waters and they were seized by the Iranians. And I have one thing to say: Gulf of Tonkin, Google it,” Rosie sneered.

Her blog claimed that “the British did it on purpose” to provide an excuse for war.

Memo to Rosie: You’ve become “The View”'s resident crackpot. Google it.
