We human beings like to think that's we're a pretty smart species in the 21st century. We can fly around the world, we've created 3D printing, and we've made it possible to communicate with someone on the other side of the world through the internet. Technology has enriched our lives. But the following ancient mysteries still baffle even the most well-known scientists of our time. Some of these are absolutely shocking.
As smart as we are, though, it appears that at some stage we've forgotten some of the things that we once knew. That's why modern-day scientists are still at a complete loss to explain mysteries that date back thousands of years. The means and methods of our ancestors baffle them.
Some of the items that appear on this list seem to have been made using techniques that would have been impossible at the time. Others are just marvels of construction which we wouldn't be able to repeat today if we tried. It's no wonder some people think aliens were involved!
When you fly by private jet charter, you experience travel comfort known only to those who know private jets. And nothing illustrates this luxury better than celebrity private jets. Stars with their own private aircraft fly fancy.
John Travolta, the star of 70s cult movies like “Grease” and “Saturday Night Fever”, is not only one of the most famous Hollywood actors, but also one of the best celebrity pilots. John Travolta is a bonafide aviation enthusiast with five private planes total, which he parks on his front lawn. His most impressive aircraft is a customized Boeing 707-138 (as pictured above), a beast of a plane that he acquired in 1998 upon his promotion to an honorary pilot of Qantas, the Australian airline.
Oprah Winfrey’s production company HARPO bought her custom-built Global Express XRS VIP business jet to provide the media mogul and her associates with maximum aviation comfort. Oprah’s private jet features designer fixtures in the bathroom and galley, along with an exquisite all-leather interior. The aircraft was designed by Bombardier Aerospace to perform as a premier long-range business jet. Custom design allowed for an enhanced cabin layout with nine cushy leather seats, aesthetically-placed lighting, and additional luxury amenities. The jet cruises through the air at high speeds, made possible by two Rolls-Royce BR710 turbofan engines, which produce enough power to send HARPO clear across the map with only one refuel stop
Tom Cruise played an elite naval fighter jet pilot in the blockbuster movie “Top Gun”, and he now indulges his real love for flying in his own Gulfstream IV, one of the finest celebrity private jets around. Cruise’s beautiful business jet accommodates up to 19 passengers, providing comfort and class with state-of-the-art furnishings and aircraft technology. The jet even automatically refreshes the air inside the cabin every two minutes. Designed by Gulfstream Aerospace, Cruise’s jet is powered by two Rolls-Royce Tay 611-8 engines, propelling the aircraft to a maximum altitude of 45,000 feet over a maximum range of 7,820 km, zipping through the air at speeds up to Mach 0.80.
Mark Cuban, business mogul and owner of the Dallas Mavericks, landed himself in the Guinness Book of World Records for purchasing his Boeing 767-277 online in 1999, making “the largest single e-commerce transaction”. Cuban modified the jet with large, custom seats to give his team’s lengthy players plenty of room while flying.
