# What if I wanted to visit all seven continents in one day?

How long would it really take?

From this point on, let's say you have chartered a Concorde. The following grid shows the local departure time, duration of the flight, the time difference and arrival time for each leg of the journey. We were able to determine the duration of the flights based on the nautical miles between destinations and the fact that a Concorde can travel approximately 1,173 knots in one hour. For example, there are 5,082.35 nautical miles between Bangkok International Airport in Thailand and Charles De Gaulle airport in Paris, France. So:

5,082.35 รท 1173 = 4:33 or 4 hours and 20 minutes

 Leg Local Departure time Duration of flight Time Difference Local arrival Time McMurdo to Christchurch 10:30 a.m. 6 hours, 30 minutes 0 hours 5:00 p.m. Christchurch to Bangkok 6:00 p.m. 4 hours, 45 minutes 6 hours 4:45 p.m. Bangkok to Paris 5:30 p.m. 4 hours, 30 minutes 6 hours 4:00 pm. Paris to Ouagadougou 5:00 p.m. 2 hours, 10 minutes 1 hour 6:10 p.m. Ouagadougou to Caracas 7:00 p.m. 3 hours, 35 minutes 4 hours 6:35 p.m. Caracas to Dallas 7:30 p.m. 2 hours, 10 minutes 2 hours 7:40 p.m.

It's easy to see that it is possible to travel to each continent in one day. In fact, if you look at the total airtime (23 hours and 40 minutes), you'll discover that, were it possible to land and take off with about a 3- or 4-minute turn-around, you would even make it in under the 24-hour time period, too. But, landings and take-offs do take more time than 3 or 4 minutes!

Using the time zones and the top speed transportation of the Concorde it almost seems too easy. With this scenario, you've even got time for a quick venture out the plane for a photo or two. But what if you could only use a 747?

 Leg Local Departure time Duration of flight Time Difference Local arrival Time McMurdo to Christchurch 12:30 a.m. 6 hours, 30 minutes 0 hours 7:00 a.m. Christchurch to Bangkok 7:30 a.m. 11 hours 6 hours 12:30 p.m. Bangkok to Paris 1:00 p.m. 11 hours 6 hours 6:00 pm. Paris to Ouagadougou 6:30 p.m. 5 hours 1 hour 10:30 p.m. Ouagadougou to Caracas 11:00 p.m. 8 hours 4 hours 3:00 a.m. Caracas to Dallas 3:30 a.m. 4 hours, 30 minutes 2 hours 6:00 a.m.

From this, you can see that it's just not possible to make a trip of this kind in one day on a 747.
