This is most likely due to a differing tension between that span and the spans on either side of it. It has more “sag” (even if only fractionally different) therefore it is more susceptible to what I referenced above.
I assume that line is communication, and the tension on them is enormous. Did you happen to get a closer look at the spiralling on it? I can’t tell by this video if it’s armouring or a grip.
I work with telecom cables. This happens when the cable isn’t rotated when hung. If it’s hung without any rotations the wind catches it and it’ll dance like this
Yeah, the Bikini Atoll was a testing ground for nukes, but that’s not the reason they are strangely hollow outlines of islands.
As far as I understand it, it’s because there were islands formed from underwater volcanic eruptions, but over time the inner islands sunk and eroded away and what makes up the island today are actually the surfaced parts of the once surrounding coral reef.
I was pleasantly surprised by the race this year. Like, cheesiness of the showmanship aside, the racing itself was highly entertaining. Especially if you ignore Verstappen and focus on the rest of the grid.
My thoughts too. I figured that the FAA would prevent this from happening for any reason except emergencies
Edit: c’mon folks, I’m not asserting that this is an emergency or that this is against regulations. I thought it was, but if this is a normal landing then it’s simply a surprise to me that it happens.
Looks like San Francisco. There are two main runways there, this is common. I think it’s just time and chance to land at the same exact moment like this.
So the Alaska is a e175 which is about 70 people vs the United which is about 170 people. It looks close because of the angle and some camera tricks. Landing on parallel runways happens all the time.
They are called Precission radar monitoring approaches and they start doing them when things get super congested. Requires us to listen to another radio so atc can tell us to break-out if someone crosses the no go zone in between the runways.
The runways are likely pretty far apart. Telephoto lenses compress depth and make objects appear closer to each other. It’s why telephoto lenses are used for portraits to make facial features look more attractive and with slightly less depth.
I’ve done this (sitting in a passenger seat), it’s normal. This video is a bit of an optical illusion, the planes are nowhere near as close as they look.
There are certain airports where it’s standard procedure.
SOP (like 99% sure). Many airports have parallel runways with more than enough clearance for two simultaneous landings. I have been a passenger in this scenario at least four times that I can think of, and I don’t fly that much. I think those were in Denver, SFO and LAX. I don’t recall there being any situation that would be considered an emergency on any of those.
Yeah, this is SFO and these runways are 750 ft / 230 m apart. Definitely not a lot of room for error, but the telephoto zoom makes this look a lot closer than it really is
It’s an optical illusion. The planes aren’t really that close together. The person who shot the video is using a telephoto lens and is zoomed way in. This compresses the space and flattens it out so it’s hard to judge distance. Also the plane in front is smaller than the one in the back which heightens the illusion. It’s a really cool shot!
Definitely the windows, but recent planes have gone with huge turbines so it’s not the most reliable tell. I don’t know Airbus well but the turbines on a 737-800 or Mac are pretty big compared to a - 300 or A320
It’s not as rare as you may think. I used to work at a weather service office located right near the end of one of the runways at IAD and it would happen a few times a day if the airport was busy and the winds were such that they were coming in from our side.
