A woman who got off an American Airlines plane after expressing concerns about traveling with a group of Arabic-speaking Iraqi men said she regretted the men were later questioned but she could not help being nervous. Leigh Robbins, 35, elected to get off American Airlines Flight 590 from San Diego to Chicago late Tuesday with her two young sons after one of the men went into the restroom and started "clunking around" before the plane left the gate. One of the men made small talk with her about being in the military, and she reported her concerns about the group to airport security before boarding. Security officers told her the men were not behaving suspiciously and left without talking to them. Pilots decided to turn the plane around without taking off after taxiing from the gate. The reasons for the decision were unclear.
