Rainbows are actually circules not arcs 🌈

It’s possible to see the whole circle of a rainbow – but sky conditions have to be just right. Plus you have to be up high.

When sunlight and raindrops combine to make a rainbow, they can make a whole circle of light in the sky. But it’s a very rare sight. Sky conditions have to be just right for this, and even if they are, the bottom part of a full-circle rainbow is usually blocked by your horizon. That’s why we see rainbows not as circles, but as arcs across our sky.

When you see a rainbow, notice the height of the sun. It helps determine how much of an arc you’ll see. The lower the sun, the higher the top of the rainbow. If you could get up high enough, you’d see that some rainbows continue below the horizon seen from closer to sea-level. Mountain climbers sometimes see more of a full-circle rainbow, though even a high mountain isn’t high enough to show you the whole circle.
Pilots do sometimes report seeing genuine full-circle rainbows. They’d be tough to see out the small windows we passengers look through, but pilots have a much better view from up front.

Emirates Airline A380 Business Class Review


My connection was 1 hour in Dubai airport so I had to run immediately to the gate “flight number EK215” rather than the business class lounge, I boarded through the door on the lower deck, walked up the staircase through first class, and then found myself in the business class cabin.

Emirates’ A380 business class cabin is massive, with 76 seats. There’s a forward business class cabin with 58 seats, and then a rear cabin with 18 seats. As you can see, the forward cabin is huge.

Emirates’ A380 business class product is in a staggered configuration, with each fully flat seat featuring direct aisle access.

I had assigned myself seat 18A, which was the window seat in the fourth to last row of the forward cabin. Emirates’ business class seats are staggered, meaning that in each row they alternate between being closer to the aisle and being closer to the window. you’ll want to select the seats closest to the window, if possible. That’s because these seats have significantly more privacy, and really feel like cocoons.


As you can see below, the seats closer to the aisle don’t have nearly as much privacy, and feel quite exposed

Meanwhile to my right was the entertainment controller, seat controller, minibar, power outlets, and more storage.

Generally speaking I find this type of staggered configuration to feel pretty claustrophobic, especially the area for your feet, which is often too small to be able to move your feet when in the reclined position.

The meal was done about 2hr30min after takeoff, which is quite long for a three course meal. Then again, it’s not like there’s much of a rush on a 16+ hour flight.

As far as the service goes, I think the crew was friendly, though I think Emirates’ service procedures in business class are way better than any other airline I’ve tried. The entire experience feels like an assembly line.

I really felt guilty asking for things “out of turn,” although the crew is so nice during the service they also looked so stressed. and has a very specific procedure. Perhaps part of the problem is that Emirates has a pretty big business class cabin.

So while it’s not the crew’s fault, there’s room for improvement on Emirates’ part.

At this point we were approaching Russia, and I decided to check out the bar at the back of business class.

In the bar there was dedicated cabin crew called Christina from “Lithuania” she was simply amazing, as a person who cannot sleep during flights I spent most of my time at the bar chatting with her and other passengers, it was like a social place with people from all around the world.


She also offered me a pre-departure beverage from a tray, with the choice between champagne, rose champagne, apple juice, or orange juice. I had a glass of champagne, and was also asked if I wanted the wine list for the flight.

It was my first time on A380 business call and that’s the reason I am posting about it !

Over all it was one of the best flights I have ever took. Emirates exceeded my expectation.

These Are the Droids You’re Looking For—Tracking the ANA Star Wars Fleet

With the recent addition of C-3PO, the All Nippon Airways Star Wars droid fleet is now complete. Here’s a quick guide to tracking all four aircraft. Track them using Flightradar24.com 🙂


Follow the R2-D2 787-9 with registration JA873A.


Follow the BB-8 777-300ER with registration JA789A.


Follow the C-3PO 777-200ER with registration JA743A.

BB-8 & R2-D2

Follow the combination BB-8 & R2-D2 767-300ER with registration JA604A.


Where they fly

The R2-D2 787 and the BB-8 777 both fly international routes from Tokyo, while the R2-D2 + BB-8 767 and C-3PO 777 are used on domestic routes. Use registration filters to track each aircraft live or visit our historical data pages to see where the droids have been.

What is ADS-B?

Skies around the world are becoming increasingly crowded. In the U.S., the Federal Aviation Administration estimates that rising numbers of flights and passengers will overwhelm the current air traffic control system by 2015, leading to an increase in delays, higher costs, and greater environmental impact.

To meet this challenge, the FAA is building NextGen, America’s air traffic control system of the future, which will make air travel safer, more efficient, and better for the environment. The backbone of this system is a new technology called Automatic Dependent Surveillance — Broadcast, or ADS-B.

ADS-B enables the widespread use of satellite-based GPS technology in aviation. It provides air traffic controllers and pilots with information that will help aircraft efficiently navigate our increasingly congested airspace.

So how does it work? ADS-B allows planes to determine their exact location using GPS. That information is broadcast to other nearby aircraft and ADS-B ground stations, which relay the information to air traffic controllers. Additionally, a signal with flight, weather, and radar data is broadcast back to the plane.

To make this possible, aircraft will be required to have equipment that continually broadcasts their position, and, optionally, additional equipment that enables the aircraft to receive those messages from other planes, as well as information from ground stations.

This continuous and nearly instantaneous cycle of broadcasts gives air traffic controllers and pilots a complete and more up-to-date picture of their airspace.

ADS-B provides updates 12 times more frequently than radar, which means better coordinated takeoffs and landings, less time sitting on the ground or circling in the air, more direct routes that shorten flight times, and fewer delays.
