American Airlines Is Using a CT Scanner To Screen Luggage At New York's JFK Airport (theverge.com)

According to American Airlines, the airline is working with the TSA to install a new bag-scanning machine at New York's John F. Kennedy International Airport. "The machine uses the same technology as CT scanners, providing a 3D image of bag's contents, and is expected to be operational in late July," reports The Verge. From the report: The new scanner, which will be used at the airport's Terminal 8 security checkpoint, will allow TSA to rotate a bag's image 360 degrees to show its contents. American Airlines says this should provide a more effective way for agents to inspect bags for explosives and other prohibited items. TSA administrator David Pekoske tells CBS News that the new machines could allow for liquids, gels, aerosols, and laptops to be left in bags. The TSA plans to have 15 of the new CT scanners at airports by the end of the year, and are authorized to purchase up to 240 of the machines, which cost $300,000 each, in 2019. The technology has also been tested at Phoenix Sky Harbor International Airport and in Boston.

      Has anyone tried to smuggle explosives into an airport and been caught?

      I think what you really want to know is if anyone has tried to smuggle explosives on to a plane, not into an airport. You don't get checked when you walk into an airport, you get checked when you go to the gates.

      And, the answer is "yes". People have tried to smuggle explosives onto airplanes. Here is a partial list of 2017 attempts:

      A checked bag containing an ammunition box with three live ground burst simulators, two live M83 smoke grenades, and one inert practice grenade was discovered at the Palm Springs International Airport (PSP).
      A live flashbang grenade was discovered in a carry-on bag at the San Diego International Airport (SAN).
      A live smoke grenade was discovered in a carry-on bag at the Raleigh–Durham International Airport (RDU). Not only do smoke grenades deploy a thick blanket of smoke, they also burn extremely hot and are considered hazmat.
      A one-pound bottle of gun powder was discovered in a checked bag at the Ketchikan International Airport (KTN). Gun powder is never permitted on an aircraft..
      Five one-pound bottles of gun powder were discovered in a checked bag at the Boise Airport (BOI).
      A ten-ounce container of gun powder was discovered in a checked bag at the Salt Lake City International Airport (SLC). While properly packed ammunition is allowed in checked bags, gun powder is strictly prohibited altogether.

      There were also about 4,000 guns that TSA seized in 2017 when stupid jackoffs (mostly rappers, professional athletes and Republican officials) tried carrying them onto a plane.

      People also like to bring inert explosive devices onto planes for some reason. A bunch of inert hand grenades, claymores, suicide vests and other goodies were seized in 2017. Also, throwing stars, daggers disguised as hairbrushes and tons of other whacky shit.

That's not saying they will actually be flying while shooting, presumably with two or three crew on the deck there's going to be someone that flies the plane and another that defends the deck from intruders.

      A locked door is a great idea but just how long will that door withstand a beating from a determined person on the other side?

I'd rather they shoot the bastard than try hand to hand combat, or make the plane jig and bob to knock the intruder off their feet. Someone besides the intruder could get hurt.

      Putting sky marshals on planes cost money. Training a pilot to go armed is often an expense the pilot will bear on their own. Just allow it with proof of training. The government doesn't even have to fund the weapons they carry, I'm guessing the pilots will pay for that out of their own pocket too. Sky marshals cost money, and a seat on the plane. Armed pilots cost nothing.

      While we are at it let's arm the rest of the flight crew. If a passenger takes all the same training, and passes all the same background checks, then let them fly while armed too. Perhaps saying this costs nothing is not absolutely correct since some government office somewhere would have to manage the licensing and such. What's quite certain is that it would be far cheaper than sky marshals, and likely more effective. A sky marshal on a plane means one armed person, and they tend to stick out in a crowd. An option to have armed crew and passengers means there could be no one armed on the flight, one, two, or ten. No one knows, perhaps not even the airlines.

      What you propose would be a lot more expensive, which is probably why it isn't done. The sensors are probably the most expensive single part of the machine, the generators aren't cheap either. I think scatter from metal objects that reflect X-Rays would be more of an issue in your design, unless you only used one emitter at a time, in which case the extra detectors might be useful to reduce the artefacts from metal objects, but the scan would take longer.

      With a rotating design the scans are fairly quick as it is, with reconstructing the final image taking substantially longer than the scan, the main benefits you'd get from faster scan is reduced motion artefacts from the patient moving, and possibly less radiation. If you are scanning luggage, neither of these is an issue.

      The maintenance issues from the rotator are minimal (how much maintenance does an electric motor need?)

      I'm not sure what chemical information you'd expect to get. X-Ray scans can give a good idea of the density of an object, but you can't infer chemical make-up from density alone.
