Boeing's upper management is being singled out as the main reason for its continued problems.
The aerospace manufacturer's CEO is being questioned in the US Senate over safety issues and allegations the company has faced this year.
Ex-employees allege the company has been cutting corners, hiding evidence from regulators, and skipping safety inspections.
Aviation researcher Boyd Group International President Mike Boyd told Mike Hosking that Boeing has stopped investing in its planes.
He says the problem is the upper management is more worried about the stock price than managing the company.
