### Fastest Way To Travel Between Two Antipodes?

Studying for my Geography final exams about the pacific ocean, I noticed that parts of New Zealand are exactly halfway around the earth from Spain. I went on to read a bit about antipodes, and I started wondering which 2 antipodes on earth you could travel between in the least amount of time. I found some great resources, including a map:

Another map:

And a Wikipedia article containing a list of some cities that are exact antipodes to each other:
http://en.wikipedia.org/wiki/Antipodes

So let's get the competition started.

Through Google Maps, I found that the antipode of Madrid Barajas Airport is in New Zealand at 4h 11 min. driving distance from Wellington International Airport. The quickest flight connection from Madrid to Wellington seems to be 31:05 hours, on Qantas through Frankfurt and Sydney. Now if you start your clock right when the airplane takes off at MAD, and assuming you need about 45 minutes to deplane at Wellington and rent a car, you'd need EXACTLY 36 hours to travel between these two antipodes.

How much further can we cut down the time? I challenge you to come up with anything shorter than 36 hours, but you HAVE to consider the time to get to the exact spot, not just between airports, unless they are exactly antipodean.

Have fun!

I've got one a little faster...

Gibraltar -> Great Barrier Island, New Zealand.

GIB->LGW d18.15 a2035 = 2h45 Easyjet
layover 0h40
GIB->DXB->AKL d21.15 a12.50 = 28h35 Emirates
layover 1h10
AKL->Great Barrier Island d14.00 a14.30 = 0h30 Great Barrier Airlines
Total = 33h40

That connection may be a little tight at Gatwick, but there is a departure 1/2 h earlier from GIB...

 Quoting Signol (Reply 1):Gibraltar -> Great Barrier Island, New Zealand.

Actually, the antipode to Gibraltar is at -36.151114, 174.651211, which is on the New Zealand mainland, or actually a few feet into the ocean. You must have done something wrong in your calculations?

Still, a drive from Auckland airport to the place takes 2:08, add 45 minutes for immigration and car rental, so your antipodes are 34:53 travel time apart, beating mine by over an hour. Let's see how much further we can get!

The Airbus A340 did make a non-stop flight from Paris to Auckland and then back over the Pacific non-stop Auckland to Paris, but it was completely empty and had everything stripped out and no passengers or freight. I seem to remember that they did it as a round the world and beat a time record but I can't remember what year it was.
There was a better way to fly it was called Concorde

Actually, going back to that Gibraltar example you pointed out: If you start your travel on this rather nice looking beach in Spain, just opposite to the rock of Gibraltar...

...then walk to the border, cross into England, and into the terminal (very short distance, 20 min. maybe), then continue as outlined above...

And end your trip on this parking lot on the beach of the Pacific Ocean...

Then you'll have traveled to 2 points EXACTLY opposite each other. Looks like a nice set of antipodes. I'd love to do this. Interestingly I've been exactly at that first of the 2 points.

You very well know that the fastest way to travel between two antipodes is to drill a tunnel (chord) between the two! Think of the fuel savings along the way...

Then we could discuss about what happens to gravity once you're in the center of the Earth (disregarding the problems caused by melting and/or burning up along the way)...

its a bloody long walk from Spain to england! I assume you mean walk to Gibraltar, which is not in england!

Just curious - If such a tunnel did exist, and you dropped a stone in it, would it accelerate all the way to the core, and then slow down to zero at the point it emerges (like a pendulum)?

(btw, OT apologies...)

I could be wrong, but I think that it would fall and then oscillate back and forth, before settling at the midpoint of the tunnel (if there is any friction) since theoretically, gravity would pull it back into the tunnel at the other end.

Assuming no friction, you could consider it a cheap way to travel!

At the exact center of the earth, gravity gets cancelled out... the value of 'g' drops as you drop don this hole, unlike surface drops. Anyway, must be pretty hot down there!

Right, and since there would be momentum built up as the object falls and the force of gravity mirrors itself on the opposite side of the center the objects speed should reach 0 on the exact other side, before falling back the other way.

This isn't perfect, the antipodals end up in the ocean by about 30 miles (or 15 if you split it evenly) but it's really close...

That antipodal chart is simply amazing...

I never imagined there were so few actual antipodal land surfaces. All of Europe, Africa and most of Asia sits in the Pacific (which shows how vast it is) and Australia fits nicely in the middle of the Atlantic ocean. North America is floating in the middle of the Idian ocean.

The only way to make the kind of Journey the OP posted is between NZ and Spain or South East Asia and South America.
I'll do my own airline. With Blackjack. And hookers. In fact, forget the airline.

OK, I have another one. Xian, China to Santiago de Chile. If you start inside Xian's terminal, and take a flight that takes 32:50 through Beijing and Toronto on Air Canada, then rent a car at SCL and drive the roughly 3:10 to the antipode near Rancagua, you'll be at about 36 hours plus whatever you need at the airport. Not better than the options above, but it's a whole new area. Seems like the magic number is the lower 30s of hours.

I found an even better one! Start off inside Shanghai's PVG terminal. Take an 28:35 flight to Buenos Aires EZE on Shanghai Airlines PVG-ORD, then US Airways ORD-IAD-EZE. At EZE, rent a car and head north to the antipode near Salto, 5:36 driving time. Total time with immigration about 35 hours. Maybe I could cut that time by including a domestic flight in Argentina, I'd have to look it up.

That would be a United flight with a US Airways codeshare.
