Darned if I can get Droneklax site to give me anything other than 12,198 for his "entry" PVG-BUE.
And it says for PUQ-IKT is 12,208.
As posted SIN-UIO is greater in distance?
Randy's mileage site seems easier to use - to me anyway!

EDIT .. now I see you were talking
KILOMETERS, not miles! We all need new jobs as mathematicians if both are required mentally! Anyway, miles, or kilometers, or yards, or inches, or roods, UIO-SIN is longer. That was based on a quick guess, so something closer to 20,000 is I am sure possible if you search a detailed atlas for tiny airports within a few 100 miles of SIN - and there are LOTS.
Good thread. TIP - the Equator literally runs right thru Quito (I have a photo with one foot in the Northern Hemisphere, the other in the Southern!) so I'd suggest leaving that as one fixed and try Kuching or something for the purpose of the exercise. Good mental exercise for us!
