{{Note|The following Nasal script can be executed via the Nasal Console or put in a separate file and executed via a menu item to easily test different aspects of reset/re-init. For the time being, you are likely to trigger segfaults/crashes or other undefined behavior (e.g. memory leaks), so it is recommended to run fgfs in a gdb session to obtain a backtrace.
