Lots of questions here: What are your goals/timelines with regards to funding (Very different than SAAS)? For a new plane won't you need hundreds of millions of dollars before you even get a prototype flying? Why haven't Boeing/Lockheed/Northrup built a plane to fly supersonic ? Is the execution of building a new plane or patents going to be your path to success ? Wasn't Warren Buffet investing in this space a few years back ?
