Passengers heard a 'whistling sound' on a previous flight on the same Boeing 737 that lost its door plug, lawsuit says

• A lawsuit says a "whistling sound" previously came from the door plug of the Alaska Airlines blowout jet.
• "This plane was a ticking bomb," the attorney, who is representing passengers on the flight, said.
• The 737 Max 9 left Boeing's factory missing key bolts designed to secure the plug, the NTSB said.

A "whistling sound" came from the door plug on a previous Alaska Airlines flight on the same jet involved in last month's blowout, a lawsuit says.

"This plane was a ticking bomb," said Mark Lindquist, an attorney representing 22 passengers who were on board Alaska Airlines Flight 1282.
