OverTheGeicoE writes "A group of students and a professor were detained by TSA at Dallas' Love Field. Several of them were led away in handcuffs. What did they do wrong? One of them left a robotic science experiment behind on an aircraft, which panicked a boarding flight crew. The experiment 'looked like a cell phone attached to a remote control car with some exposed wires protruding.' Of course, the false alarm inconvenienced more than the traveling academics. The airport was temporarily shut down and multiple gates were evacuated, causing flight delays and diversions."
