Terms
Last updated 9 October 2026
Plain terms for buying and using the book. If anything here is unclear, write to us at hello@planoaviation.com.
Who we are
Plano Aviation is a brand of Robustors (robustors.com). We publish the ebook Nothing on a Plane Is an Accident.
Who sells the book
Gumroad is the merchant: it takes your payment, charges any sales tax and delivers the file. Gumroad’s own terms apply to the purchase. We are responsible for the book itself.
What you get
A PDF ebook, and access on this website to the 3D model and the one-minute answer film for every case.
What you may do with your copy
- Read it on all your own phones, tablets and computers.
- Print pages for yourself.
- Quote a few lines in a review or a school project, and say where they came from.
Please don’t share the file, upload it anywhere or sell it. If you want to use the book with a class or a group, write to us first.
The 3D models and films
They come free with the book and open on this website. We work to keep them online and we may improve them over time. They are for exploring and watching here, not for downloading or reusing.
Accuracy
Every fact in the book was checked against the sources listed in each case. If you find a mistake, tell us and we’ll fix it in the next free update. The book is for learning and curiosity. It is not a flight manual and not training for pilots or engineers.
Names and logos
Airline and maker names are used only to say which aircraft is which. This book is not made or approved by any airline, maker or government agency. Our aircraft pictures are painted plain white, with no airline’s colors or logos.
Refunds
See the refund page.
Changes
We may update these terms. The date at the top shows the latest version. The terms that applied when you bought still apply to that purchase.
