    Celera 500L claimed performance almost as impressive as online comments are negative — General Aviation News
    https://generalaviationnews.com/...performance-almost-as-impressive-as-online-comments-are-negative/
    “Laminar, shlaminar: The Celera 500L is essentially a Zeppelin with wings,” claims Dennis R. “The design predates the Wright brothers by three decades, and was patented prior to 1900. Nothing wrong with that, but let’s not get carried away either. There’s nothing novel or revolutionary about reinventing the blimp. Let’s just hope it doesn’t meet the same fate as the Hindenburg in 1937.”

    One of the stronger negative comments came from John Schubert. He posted to both AVweb (as John S.) and Boldmethod. “I thought about this a few days, and came back ticked off. This ‘airplane’ is vaporware. Let us not pretend otherwise. Why would they go to the trouble of making the vaporware? Because there are many naive investors with many millions. Family money, oil money, etc. I have seen money plundered from naive investors in my own work experience. A ‘news article’ helps them dupe prospective investors.” The comment continues for some length.

    Otto Aviation’s Celera 500L Completes 31 Successful Flights | Flying
    https://www.flyingmag.com/story/aircraft/otto-aviation-celera-500l-31-flights/
    A truly unique aspect of the Celera 500L is the aircraft’s 22:1 glide ratio, obviously quite useful should the single powerplant fail enroute. Similar to many glider aircraft, Otto Aviation says the 500L can glide up to 125 miles in still air with the engine shut down.
