Indeed - you have discovered the Truth - if you commit aviation and *not* at some stage of the flight become inverted you should either a) be strapped in the back of something large, with access to a drinks trolley and a choice of movies or b) be strapped at the front of same and being paid to keep it from becoming inverted, lest it upset the drinks trolley. If (a) or (b) do not apply, then you're simply wasting fuel.
