Canopy Sill Longeron Cracks Caused The Grounding Of 90 USAF F-16s Within The Past Year

Cracks on the canopy sill longerons are affecting the U.S. Air Force inventory of F-16s.
An interesting article recently published by the 140th Wing Public Affairs exposes an issue affecting the U.S. Air Force F-16 Fighting Falcon fleet: canopy sill longeron (CSL) cracks. The CSLs run the full length of the cockpit and support the structure between the frame and skin of the aircraft, preventing tension and bending of the fuselage.

Aging airframes are more subject to structural issues and according to the article, the structural integrity of the longeron is getting worse: CSL cracks were identified on 90 aircraft across the U.S. Air Force within the past year.

“The aircraft is immediately grounded when the canopies crack,” Tech. Sgt. Taylar M. Reilly said. “A crack can spread, and if both sides break, the whole nose could fall off.”

By means of shrewd lies, unremittingly repeated, it is possible to make people believe that heaven is hell - and hell heaven. The greater the lie, the more readily it will be believed.

The receptivity of the masses is very limited, their intelligence is small, but their power of forgetting is enormous. In consequence of these facts, all effective propaganda must be limited to a very few points and must harp on these in slogans until the last member of the public understands what you want him to understand by your slogan.
