There's a renewed call for Boeing to be prosecuted after being grilled in the US Senate over its recent safety issues. 

US Justice officials have until July 7th to decide if it lays criminal charges. 

Family members of the 346 victims of two separate crashes involving Boeing planes five years ago were also at the hearing. 

US Correspondent Katherine Firkin told Mike Hosking that they're calling for criminal liability for the company, specifically the upper management. 

She says they want Boeing to be fined almost US$25 billion, and for officials to move forward with criminal prosecution.
