Eleven U.S. passengers who survived the crash of Aeromexico Flight 2431 filed separate lawsuits on Monday in Chicago against the Mexico-based airline.

The airline's Embraer 190 with more than 100 people on board crashed on July 31, shortly after taking off from an airport in the northern Mexican state of Durango during a severe storm.

All passengers survived the crash but many suffered injuries. Many of them are reported to be U.S. citizens, with some living in the Chicago area.

"All of the people on this flight have the right to know exactly what caused the plane to crash. A plane just doesn't drop from the sky because it's raining hard," said Thomas A. Demetrio, co-founder of a law firm who represents the 11 victims.

Last Thursday, the same law firm filed the first lawsuit against the airline in the U.S. on behalf of another Chicago area survivor of the crash, alleging Aeromexico was negligent in improper take-off.

Francis Patrick Murphy, another attorney with the law firm, said on Monday that weather, to some extent, is always a factor in flight operations.

"However, safe flight operations depend on how the airline and its pilots monitor, respond to and correct for severe weather conditions, both in the pre-flight and inter-flight decision making process, in order to avoid a mishap," he added.
