Elon Musk suggested that SpaceX will abandon its plans to land the company's Dragon capsule on Mars - a mission the company had been aiming to do as early as 2020, The Verge says.

"Elon Musk has had no contact with Philadelphia officials on this matter", Mike Dunn, deputy communications director for the city of Philadelphia, told Business Insider.

While fielding questions from the crowd Musk said he saw a way for his Boring Company to overlap with colonization plans. The entire route from New York City to D.C., he claimed, will take just 29 minutes.

"Just received verbal govt approval for The Boring Company to build an underground NY-Phil-Balt-DC Hyperloop", Musk said.

After New York-to-Washington, Musk said he would probably proceed with a hyperloop from Los Angeles to San Francisco and one in Texas.

Getting from New York City to Washington in under a half hour perhaps got a step closer Thursday.

"City center to city center in each case, with up to a dozen or more entry/exit elevators in each city", he said in another tweet.

SpaceX's chief said Wednesday that the first launch of its big new rocket is risky and stands "a real good chance" of failure.

One of Musk's other endeavors, the Boring Company, is also working on new plans to build fast trains in tunnels underneath major cities.

The White House and Transportation Department did not immediately comment on Musk's tweet.

Hyperloop uses magnetic levitation allowing you to glide at airplane speed in pods moving through tunnels above or below ground.

"You can build a tremendous amount underground with the right boring technology on Mars, so I do think there's some overlap in that technology-development arena", Musk said.

White House National Economic Council Director Gary Cohn in April praised the idea of Musk using tunnels to speed rail transit on the densely populated east coast of the United States and also to cut traffic congestion in Los Angeles.

Shortly after Musk's tweet, de Blasio's press secretary Eric Phillips responded to Musk's announcement with his own tweet suggesting the mayor knows nothing of the verbal approval.

Musk described the first demonstration flight, which is expected to occur later this year, as "guaranteed to be exciting".
