Paramotor = paraglider + engine.
Strictly speaking that's not quite true as they follow divergent development paths. Flying a paramotor without the motor would be an uncomfortable experience and vice versa. What they have in common is they're both wings used to fly people around - but then so is a 747.
I raise the distinction since paragliders are largely flown under club auspices & as a collective flying community go to some lengths to maintain good relationships with landowners and other stakeholders. Paramotoring doesn't really exist within the same structure hence the odd rogue buzzing the beach drawing a bit of sniffy irritation such as above. 100% of pilots are out for a good time, slightly less than that are consistently sensible and exhibit empathy toward others, but let's maintain a sense of perspective.
