Air travelers across Iowa — and nationwide — are stranded following this morning’s terrorist attacks in Washington D-C and New York. The F-A-A ordered all pilots to land their planes after the acts on the East Coast. Flights were leaving as usual earlier this morning from the Quad City International Airport in Moline, Illinois, but all are now grounded. Some planes have been diverted from other airports to the Q-C Airport. A rental car agent at the airport says from her vantage point, the place is deserted.Radio Iowa’s Dar Danielson was at the Des Moines airport and talked with passengers whose flight from Indianapolis was ordered to land. They said they had no idea what was happening until they got on the ground.One passenger whose plane was unexpectedly grounded says when travelers learned the news, they were shocked, and says the U-S should retaliate against whoever committed the terrorism. Passengers quickly turned on their cellphones or headed for pay phones to call relatives once they got off the plane. After picking up their luggage, they had to find a place to stay or a ride to their final destination. Several hundred were able to get on buses to Minneapolis.
