More passengers joined a lawsuit against Boeing and Alaska Airlines over the frightening midair blowout in January.
The amended lawsuit now includes 22 people including an unaccompanied minor who was on the flight.
It also reveals new allegations.
The suit claims ‘a whistling sound’ was heard on a prior flight.
The new claims were brought by attorney Mark Lindquist, who said: “Passengers apparently noticed the whistling sound and brought it to the attention of flight attendants who reportedly informed the pilot or first officer.”
A pilot then checked for cockpit alerts, but all looked normal, and no further action was taken.
Lindquist filed the original lawsuit last month.
It is seeking damages for personal injury and claims of ‘fear, trauma and extreme distress.’
“A plane was delivered by Boeing to Alaska Airlines without four critical bolts, which was essentially a time bomb,” Lindquist told Fox TV.
