Following his $44 billion Twitter investment, Elon Musk has added a $78 million jet to his fleet of private planes.

According to reports, Musk has ordered the Gulfstream G700, which would replace his existing jet, the G650ER. Musk presently owns four planes, three of which are Gulfstream models and a Dassault 900B, his first acquisition.

The G700 can fit about 19 people, which is more than the average private jet because it is "stretched." The U.S. Sun reported that this makes it the longest "purpose-built" private plane in the sky. It also has an amazing range of flight and speed.

According to estimates, the G700 can go 7,500 nautical in a single flight, enabling it to visit two continents in a single journey. It can also reach a maximum speed of Mach 0.925 while cruising, which is somewhat under breaking the sound barrier.

Aside from its impressive functionality, Elon Musk was also drawn to the luxurious interior since it is so stunning.

Inside Elon Musk New Private Jet

According to Gulfstream, the G700's cabin has a bathroom, a kitchen, forward seating, an entertainment suite, a dining area, and a stateroom with an en suite bathroom.

The stateroom has a single or double bed, while the en suite bathroom features multiple cupboards for amenities and valuables, a leather-seat toilet, and a full-length mirror.

The bathroom may also be modified to contain a shower, making it one of the few private jets with enough space to accommodate one, Daily Star reported.

The billionaire, who flew 150,000 miles in his G650ER in 2018, is unlikely to leave the new aircraft in the hangar alone.

Elon Musk Tries to Stop a Teen From Tracking His Flight

Earlier this year, Jack Sweeney, 19, created a Twitter account called @ElonJet, tracking Elon Musk's private jet flights worldwide.

"Can you take this down? It is a security risk," Musk began talking to Sweeney over Twitter DM.

It was a late-night message that arrived at 12:13 a.m. Sweeney's time, but the college freshman did not let it bother him. 

"Yes, I can, but it'll cost you a Model 3 only joking unless?" he replied nearly seven hours later.

One of Sweeney's 15 flight-tracking accounts is @ElonJet. Every time a specific jet takes off or lands, Sweeney has built bots to read the data and tweet about it.

Each one features a renowned individual, and practically all of them are involved in technology, such as Jeff Bezos and Bill Gates. But the most famous account is @Elon, which has more than 480K followers.

"I don't love the idea of being shot by a nutcase," Musk told Sweeney. Their conversation continued until Musk asked Sweeney how much he was making from the Twitter accounts, to which the teen answered not more than $20 a month.

According to Protocol, the Tesla CEO offered him $5,000 to delete the account and help Musk to keep up with "crazy people" from tracking his location.

The teen answered: "Any chance to up that to $50k? It would be great support in college and would possibly allow me to get a car, maybe even a Model 3."

Elon Musk replied that he'd think about it, but it seems they had not made a deal yet, as @ElonJet is still active on tracking Musk's flights.
