MacBook Air stumps TSA agents, owner misses flight The suspiciously thin, port-free laptop sends airport security into a tizzy, until cooler heads prevail. Maybe it's time for some tech briefings at the TSA, no?On his blog, programmer Michael Nygard (by way of the Unofficial Apple Weblog) writes that during a recent trip through the airport, his solid-state MacBook Air stopped TSA agentspuzzled by its lack of rear-facing ports or a standard hard drivein their tracks. Nygard said the agents put him and his suspicious "device" in a holding cubicle as security staffers huddled nearby, looking at X-ray printouts of the sinister-looking Air and scratching their heads. A younger TSA agentwho, apparently, was aware of Apple's newest laptoptried explaining to the group that the Air uses solid-state memory in place of a traditional hard drive. The senior staffer, however, was still reluctant to let it go: "New products on the market? They haven't been TSA approved. Probably shouldn't be permitted," Nygard writes. Finally, after booting up the Air and running a program, the agents let Nygard go, he saidbut only after he'd missed his flight. I've been hearing stories like these all too often, which leads to the question: how exactly are TSA agents being trained, anyway? How about, I dunno, some regular briefings on the latest gadgets that might be making their way through security checkpoints? And while TSA agents are wasting time fussing with laptops, undercover investigators with bomb parts in their bags have been sailing though security checkpoints.
