Is Elon Musk working on an “Iron Man” flying suit?

It’s a question that has been asked before: Is Tesla and SpaceX CEO Elon Musk the real-life version of “Iron Man?” If this tweet from Musk himself is anything to go by, the answer might be “yes.”
On Wednesday, CNN reported on Musk meeting with Defense Secretary Ash Carter at the Pentagon. Referring to the article’s headline wondering what the meeting was about, Musk tweeted: “Something about a flying metal suit…”

The Pentagon would only respond that the meeting was about “innovation.” Musk has of course been looking to attract government business for SpaceX, which recently secured an $82 million military contract to launch GPS satellites into orbit.
There is no word on whether Captain America, the Hulk, or the rest of The Avengers were in attendance.
