    route - HKG - ORD
    flight aware is showing the route with dashed blue.. why question is why not the red line? if the answer is to keep some mother earth under the plane for emergency, why not the yellow line? seems to me the dashed blue line is way round about way of reaching ORD. what am i missing? jet stream? santa?

    That map is a mercator projection. Look at a globe and the blue path will make more sense.

    I punched the route (VHHH-KORD) into ForeFlight online, which uses the Mercator projection, and ForeFlight Mobile, which shows a 3-D globe view. Note that the route lines pass over all the same places... Here's the route line, viewed from directly overhead:

    Here's the route when viewed from closer to the equator:

    For reference, London Village, Kiribati, appears below the halfway mark here but is actually slightly north of the equator.

    Finally, here's the Mercator projection:

    If you are referring to the graphic I had posted, no idea, I drew it, keeping Mother Earth under the route

    Sorry... but... even if you're over the ocean, you are still over Mother Earth.

    It's the scenic route. A little bonus the airline throws in for free.

    What exactly do they teach to fill up the school days nowadays? And I'm not referring to flight school. :rolleyes:

    Never thought about it before, but the graphic above made me realize that when my unit sent us to RVN in 1969, we flew in our RC-135 from Forbes AFB to Alaska thence to Japan then on to Tuy Hoa RVN which was the shortest route.

    Thanks for posting that.

    I was surprised too. But I didn’t know about the great circle and small circle until ground school.
    But surprised because it was the start point of the navigation section in the textbook.

    And I think it was on the exam, and all test exams.

    And just a minor nit... when someone talks about “crossing the pond” they are referring to the Atlantic. Here we would just say “crossing the Pacific.”

    And for "fun" I punched this all into ForeFlight.

    The great circle route is 6,773nm.
    The "Pacific rim" route is 7,265nm (I tried to go roughly as it's drawn - VHHH DONAR DIROS CEVNO MALAS SPYSR KORD).
    The "looks direct" route is 8,103nm!

    And everyone thinks that the "world" changes at the International Date Line....Wrong! It is at 30 West. If you flown internationally then everything changes there. Slightly TIC.

    I have a picture I took as I crossed the Equator and the International Date Line exactly and there is a story about a ship that crossed that exact point exactly at midnight on December 31st 1899. The bow of the ship was in 1900 and the stern was in 1899 both on different days and different centuries. Crossing the Date Line exactly at midnight can cause you to skip a whole day either way.

    Hey, it's sometimes boring over the ocean!

    Except the century and millennium changeover is year 00 -> 01, not 99 -> 00

    There is no year 0, so the 1st century (100 years) is from year 1 to year 100. The 2nd century is from 101 to 200, etc...

    The number of people I had to explain that to circa 1999-2001 was rather large.

    They all thought the 21st century began on 1/1/2000.

    They all wanted to party on 12/31/1999 like it was 1999. They thought a silly song meant something.

    The Y2K issue compounded it.

    The media sometimes even referred to 2000 as a new century/millennium.

    When 1/1/2001 came around and I said it was the start of a new century and millennium they thought I was a year late.

    Some people are stupid.

    But if you ask them to count to ten, they will start with one, not zero. So they really should get it.

    They actually make people fly several hours longer just to maintain the lie that the earth is round.
