The crew gave the students "multiple chances" to heed preflight instructions.
"They pilot warned them. They did not comply. They thought it was a joke. You know, it wasn't a joke," Rinschler said.
"I've never seen this," he added. "It's a commuter flight. There's no families on it."
Rinschler didn't witness any anti-Semitic events. "Absolutely not," he said. "There was not one ethnic slur from anyone on the flight crew or anyone who was inconvenienced for two hours.
"If they were adults, they wouldn't have even had that many chances. That's the bottom line," Rinschler said.
One chaperone pleaded with the pilot and security for another chance.
"One chaperone --- not two, not eight --- one talked to them asking for a second chance. The pilot said, 'You had a second chance, you had a third chance. There's other people; we have to go. It's not stopping,' " Rinschler said.
Another student in the group, Michael Mamiye, said he was one of the first to be kicked off the plane. He said a flight attendant did not give him a chance to turn off his cell phone before asking him to "get off the plane."
The same flight attendant then told the captain that the students were "making trouble" and not turning off their phones, he added. The captain didn't come out of the cockpit until the last second when he asked the group to leave, Mamiye said.
According to Mamiye, he and his classmates were quiet and were sitting down as they were told. And when they were asked to leave, they left in a respectful and orderly fashion.
"We were more behaved than kids should be," he said.
Both Beyda and Mamiye said the airline's customer service did its best to accommodate the group by getting them on the next available flights. But the group had to be split up and they were in transit for a total of 12 hours, Mamiye said.
