More on that plane
A Presentation (also mentioning the Honda Jet) The sound of that aircraft was very distinctive, that engine was not used anywhere else and the noise significantly reduced when it flew over you, as the wing was shielding it, so at the point when all other aircrafts were loudest, that one got quieter. You cound not miss it.
