The challenge with a statement such as this is that it's stated like it's a natural law ("you can't fly aircraft when you're bankrupt"), rather than the result of a particular set of legal structures in a particular country. In the US, for example, you can certainly fly aircraft if you are undergoing a so-called "Chapter 11" bankruptcy (designed for reorganization.)
