The sources told Reuters that senior managers at the Hawthorne site were repeatedly warned about the dangers of rushing the engine’s development, along with inadequate training of staff and testing of components. The part that failed and struck the worker had a flaw that was discovered, but not fixed, before the testing, employees said.
