Check out the $30 million Gulfstream 450 that can fly from London to Seattle on 1 tank of fuel

For many years, Gulfstream has been one of the pioneering private jet manufacturers in the world, bringing new and more advanced planes to the market with surprising frequency.

The G450, a $30 million (£19.5 million) jet, is built for both comfort and range. It can travel up to 4,350 nautical miles, or roughly the distance from London to Seattle, on a single tank of fuel. You don't have to worry about leaving friends behind, either. There's enough room for 19 people.

Private jets have become a popular choice among companies and individuals who want to be transported from continent to continent seamlessly. While the 2008 crash impacted sales, over 600 jets were sold in 2014 with more expected this year.

Here's what the G450 looks like inside.
