Boeing rejects engineer's warning of potential long-term safety issues in Dreamliner manufacturing

Boeing engineer Sam Salehpour alleges shortcuts taken when manufacturing 787 Dreamliner jets could become safety issues as planes age
Salehpour claims excessive force used to close gaps in fuselage assembly, causing deformation in composite material
He worries this could lead to premature failure of the composite over time
Boeing says "claims about the structural integrity of the 787 are inaccurate"
Over 1,100 Dreamliners operating globally have transported over 850 million passengers, Boeing states
