Fourteen people were killed in the crash of a plane that spent weeks undergoing maintenance in San Antonio.

Lack of maintenance and the push for profits were among the causes for the November 4 crash of a UPS cargo plane that killed 14 people, according to several UPS workers who work at the Louisville, Kentucky hub and who spoke confidentially with the World Socialist Web Site.

A fleet of planes that UPS grounded after a deadly crash isn’t expected to be back in service during the peak holiday season due to inspections and possible repairs, the company said Wednesday in an internal memo.

Aviation attorney says incident raises questions about ‘profit over safety.'

Attorneys representing two families will file a wrongful death lawsuit against UPS for the Nov. 4 plane crash.
