RAeS Alan Bristow Memorial Lecture: An introduction to the Lilium jet 

Do your dd especially about Lilium

You have time for comment, but no time to visit lilium website 😂

@@mariusmartinsen2064 how do you know I haven't reviewed the website? In fact I did. Only a few pages on the business model available in the "corporate presentation". Bold claim of $3 CASM (cost of available seat mile). Multiplied by 6 seats that's $18 cost per mile at 100% load factor. Meanwhile Southwest reports $24 per mile and they have huge economy of scale in comparison. No discussion at all of revenue available per seat mile (RASM). Where are the analyses? Bold claims of 3700 aircraft p.a. There isn't enough viable (capable of producing a market) vertiport space in the world for that. Indeed, just from a pure real estate perspective that's extremely improbable. Make the analysis public, otherwise it's just all hand waving. The time savings claims in the corporate presentation are ridiculous. The Lilium times represent only air travel time. There is no door-to-door time analysis. Look at door-to-door and all of a sudden ground transport looks a lot better, and a lot less expensive. Nothing makes sense. The joke is on the investors...
