In the interest of pure research, we debated booking a flight, but, the $10,000 (give or take a few dollars) ticket price for the New York to Paris or London trip put our accountant into a bit of a snit. So much for job perks.
To cross the Atlantic it takes a mere three hours and 35 minutes. If you want to work it out yourself, here are some numbers: the supersonic plane flies at 2180 km/h. But, its take off and landing speeds are, of course, much slower. It takes off at about 362 km/h and lands at 305 km/h. Now you just need to find out the distance between New York and Paris. Good luck.
