Pilots warned smoke could penetrate cabin if Boeing 737 Max planes have a bird strike

At least two major airlines have alerted their pilots to the potential issue of bird strikes causing smoke in the passenger cabin of Boeing 737 Max planes. In February, Boeing informed Southwest Airlines and American Airlines about the problem, and both airlines subsequently passed on the alerts to their pilots. The documents obtained by CNN reveal that Boeing received reports of engine failures after bird strikes, which could result in smoke and fumes entering the cabin through the air conditioning system. The incidents raise concerns about the ongoing issues with the 737 Max aircraft, which have faced manufacturing and design challenges. Boeing and engine maker CFM International are cooperating with investigations into the incidents.
