Interesting, although challenging to see it actually land somewhere. And with a 23 minute hard deadline, if you were backed up at the drone landing pad at work, well you would not want to idly wait for traffic ahead to clear up :-).<p>Also very curious about those motors. Given a 260 lb passenger limit, the total system is probably 500 - 600 lbs and you then need to move 650 lbs of air through three engines (if you want engine out recoverability). So a single engine generating a nominal 200 lbs of thrust? So 800N over 23 minutes is about a megawatt if I did the math correctly. Not sure if you can store enough energy in that volume at a low enough weight to meet their specs. But I&#x27;d love to see it fly.<p>[1] Great discussion of airplane engine power -- <a href="http:&#x2F;&#x2F;www.aerospaceweb.org&#x2F;question&#x2F;propulsion&#x2F;q0195.shtml" rel="nofollow">http:&#x2F;&#x2F;www.aerospaceweb.org&#x2F;question&#x2F;propulsion&#x2F;q0195.shtml</a>
