4. Hermeus Hypersonic Aviation

Hypersonic flight is an old idea but it’s become a resurgent topic in the world of aviation in recent years, with some calling it the “future” of air flight. This form of flying puts aircraft into, where they’re able to skim across the sky at speeds exponentially faster than commercial airliners currently travel today. Altman has recently made investments in a company, Hermeus Hypersonic Aviation, which says its working on developing commercial hypersonic jet airliners.
Score: Altman investment most likely to be featured in the next Top Gun sequel.
