Boeing 737 Max 9 planes face more delays in flying again

Details: The FAA said it will "conduct a thorough review" after Boeing submits the revised inspection instructions.

• "The safety of the flying public, not speed, will determine the timeline for returning the Boeing 737-9 Max to service," the FAA said in its update.

The other side: Boeing CEO David Calhoun told employees on Tuesday that the company would first be "acknowledging our mistake" and that they would "approach it with 100% and complete transparency every step of the way," per the Wall Street Journal.

Catch up quick: Alaska Airlines Flight 1282 — a Boeing 737 Max 9 — returned to Portland International Airport shortly after takeoff this past Friday after a "plugged" emergency exit door flew off, exposing passengers to open air, Axios' Alex Fitzpatrick reports.

• The aircraft, however, landed safely without fatalities.

• Over the weekend, the FAA ordered a "temporary grounding of certain Boeing 737 MAX 9 aircraft operated by U.S. airlines or in U.S. territory."
• The FAA then announced on Monday that the Boeing 737 Max 9s would remain grounded until "operators complete enhanced inspections."
