A pilot flying a Delta Air Lines regional jet on Friday apologized to his passengers after making a hard turn to avoid colliding with a US Air Force B-52 bomber, audio from the incident shows.

The incident occurred on SkyWest Flight 3788, which was operating as a Delta Connection flight, from Minneapolis, Minnesota, to Minot, North Dakota, SkyWest said in a statement.

The flight landed safely in Minot “after being cleared for approach by the tower but performed a go-around when another aircraft became visible in their flight path,” the statement read.

    So why didn’t the military tower catch the helicopter in that DC crash? The FAA failed but the Army also failed? Two failures?

      I’ve not read the report, but there’d only be one tower responsible for the airspace. Iirc, it was an FAA tower. What I heard happened was that the helicopter didn’t follow the tower’s instructions. But, again, I’m months out of date on that incident.

      Imagine airspace like a tray of cookies baked too-close together. Some are bigger than others, some are weird shapes, some are sugar cookies, some are chocolate. But it’s a tray full of cookie. There’s only one cookie at each spot.

      To stretch the metaphor further, imagine an ant walking across the tray. It’s still only on one cookie at a time and it doesn’t care if it’s chocolate or sugar. At the edge of a cookie there’s a handoff between cookies, where cookie A says “hey, cookie B, an Ant X is about to walk on you. Don’t let them crash into any other ants, k? They’re your responsibility now.”

      Anyways, I’m going to go let my caffeine kick in.

        lolwut? Cookies with ants on them. I just don’t understand how there’s a military ATC and a civilian ATC and they aren’t sitting in the same room. They should be sitting in the same room.

          Why would they sit in the same room? They’re managing different airspace. There’s over 250 towers, they can’t all sit in the same room.

            OK, figuratively. From this it seems like there are two (more?) systems that are both sharing airspace that don’t know what the other is doing. That’s all I mean about “sitting in the same room”. Mabye a zoom call?

            You say “different airspace” but there’s only one airspace. It’s the one the planes are flying in.

              No, like I said, they’re using the same systems, the same software, the same hardware. People at different towers talk to each other on the phone and on the radio, especially during handoffs between airspaces. The computers talk to each other. IIRC the information from one tower’s radar is shared with other towers. They’re not parallel systems, it’s all the same system.

              edit: I’ve been using “airspace” to mean “volume controlled by a tower”. There’s many airspaces.

                OK, I get it. There’s FAA and then there’s Air Force? Is there also Army and Marines and Navy? Why don’t they all combine and make one super Voltron of airspace management?

                  To quote myself

                  I’m not sure why it is like that nowadays. I guess in the beginning of ATC in the US it made sense for air bases to control the nearby airspace, and it probably just went from there, with maybe consolidation of towers as a cost-cutting measure along the way.

                  Also,

                  IIRC, the Army and Navy also operate their own ATC Yes, there is also Marine-run ATC.

                  Spitballing:

                  • institutions don’t like losing control
                  • Many towers are located on military bases
                  • military air traffic controllers need to learn the ropes someplace that isn’t an aircraft carrier or active deployment
