Boeing (BA) has been forced to publicly apologise after internal communications suggested employees were aware of issues with its now grounded 737 Max plane before disaster struck.

Boeing on Thursday published over 100-pages of internal communications as part of the US Federal Aviation Authority (FAA) and Congress’s investigations into issues with the 737 Max.

The planes have been grounded globally last March following two fatal crashes that killed all passengers.

The emails and memos are highly embarrassing for Boeing and likely to lead to more questioning from politicians and regulators.

“This airplane is designed by clowns, who in turn are supervised by monkeys,” a chat message from April 2017 reads. Another message from the same exchange describes working on the plane as “patch[ing] the leaky boat.”

“This is such a shit show,” one employee wrote to another on a chat system in mid-2018.

“Totally,” a colleague replied, “I’ll be shocked if the FAA passes this turd.”

‘This airplane is ridiculous’

The emails paint a picture of a company rushing to get approval for its plane and pushing to have the lowest possible training requirements for the 737 Max. Less training would make the aircraft cheaper for clients.

In an exchange from 2018, employees talk about a “culture issue” at Boeing, complaining there was “a culture of ‘good enough’ and that is an incredibly low bar.”

Another message from 2018 reads: “They fail to understand that the pilots subjective feedback is as important as providing solitary test conditions that pass or do not show the full picture.”

An unnamed employee said he would “struggle to defend the sim[ulation training] in front of the FAA next week.”

“I still haven’t been forgiven by god for the covering up I did last year,” another message in the same exchange reads.

“This airplane is ridiculous,” an employee wrote to another in one message. “We are having issues with every update we do.”

Employees repeatedly talk about using “Jedi mind tricks” to convince regulators and customers that their training proposals are safe.

“At this point point there are more nails than wood in the coffin,” a message from 2018 said.

‘Completely unacceptable’

Boeing chief technical pilot talks about being “pressured into” accepting training guidelines that he admits may leave gaps for pilots. Another employee talks about not sharing certain information with the FAA because “we don’t want to indicate to the FAA that our design conflicts with pilot expectations.”
