Nope. It was the Ground Sequencer, part of the pad. Nothing to do with Boeing. Also, the first launch attempt on May 6 has nothing to do with Boeing.

Two attempts are open: Launch Time June 5: 10:52 a.m. EDT, 1452 UTC, 16:52 CEST / June 6: 10:29 a.m. EDT, 1429 UTC, 16:29 CEST. Launch Window: Instantaneous Launch Window

Most users watching on their cell-phones. They find it and watch. Not reading content or information because it is not to see well. Also, a lot are newbies in the fields who never saw such. That is the reason why. And even you did not read the info, because all info is given. ;)

You mean with "Antennas" the Launch Tower or Errector? Well, if you would put three around a rocket, the rocket would collide. A launch tower needs always to "go away" from a rocket. The rocket is doing lift-off straight first, and when you see it looks like the rocket does make a short sidemove on the pad. But, it is not the rocket, it is the pad which is moving away from the rocket, because of Earth rotation. So, doesn't matter where you launch, a launch tower has always to be placed "East" of the rocket because of Earth roation (from the west to the east), that during the lift-off, the tower will move away from the rocket. Now think about, if you would have 3 "launch towers". Hopefully, that answers your question.

@@Space-Affairs I meant the rocket

@@comcastjohn Then we do not understand what you are talking about. There is no antenna on the rocket. Receivers and senders are integrated in the rocket's fuselage. When you are talking about the "honeycomb" structure which you see in the image on the left side on the rocket, these are grid-fins which are deployed after staging and helping the rocket to steer through the denser layers of the altitude. There are four of them installed, always in 90-degree angle from each other.

Well, we spoke with Rico, but they are at the moment on Klendathu, as always. But he promised, they will end your problem, soon.
