Investigators have determined that there was no terrorism involved in an incident that caused a US Airways flight from New York to Phoenix to be diverted to St. Louis.
US Airways flight 457 landed at Lambert Airport just before 8 a.m. Tuesday after crew became concerned about the activities of three male passengers.
All 128 passengers were re-screened, the plane was checked and the plane took off for Phoenix a little over two hours later.
