Exosonic , a startup developing supersonic commercial air travel and UAV technical school , is hoist down after five year of operation .

“ Although the founders and team still trust in the need / desire for quiet supersonic flight and ultrasonic drones for the US Department of Defense , without further customer support for either concept , the companionship can not sustain the cash needs to make further advancements,”the update says .
Exosonic was founded in 2019 by Norris Tie , a propulsion engineer who dilute his tooth at blossom like Northrop Grumman and Lockheed Martin ; at the latter company , he reportedly worked on the low - boom X-59 aircraft for NASA .

As Exosonic put it onLinkedIn , “ Without further government bread and butter for its nigh - terminal figure ultrasonic UAV development , Exosonic can no longer corroborate the uppercase require to further advance the concept . ”
Tie support that the caller has get some pastime for potential IP purchases .
