Boeing Whistleblower Alleges Production Flaws in Boeing Jets

New Boeing whistleblower, engineer Sam Salehpour, alleges production shortcuts and structural flaws in 787 and 777 jets
Claims parts of planes' fuselages are being improperly fastened together, which could weaken aircraft over decades
Has been raising issues with Boeing management for years but says they weren't listening
Boeing strongly denies claims, says issues have undergone engineering review and do not present safety concerns
Salehpour says he will testify to Congress next week and provide evidence
