Snopes may have 'debunked' that, but the lady was interviewed by Michael Savage last evening. She was unwavering in what she said she saw. She also said 'local officals' sided with her, but their Washington bosses were the ones who said it didn't happen.
She still contends that the Syrian musicians were doing a trial run. She said the flight attendants were concerned enough to notify the pilot, and that 'officals' were at the plane as soon as it landed.
Snopes is compiled by a couple of leftists with an agenda. I'd be more discerning about what they "debunk".
