A frightening video shows ten Boeing engineers admit they would not fly on the 787 Dreamliner jets they were building like the Air India plane that crashed Thursday.

Workers at the South Carolina plant alleged the Dreamliners were being built by 'underskilled' and 'uncaring' factory workers who were in 'some cases on drugs'.

One whistleblower claimed '90 percent' of the problems reported on the 787 plane were 'getting swept away' and 'hushed up'.

The 2014 footage, which was first published by Al Jazeera last year, has resurfaced in wake of the tragic Air India plane crash that killed at least 265 people on Thursday.

It was shot in the same plant where the ill-fated Air India plane was constructed. That Dreamliner flew for the first time in 2013 and left the plant in January 2014 bound for the Asian airline.
