Quiet Airplane.

A light airplane flew over a few hours ago,was low and oddly quiet.
They normally make a racket from miles off.This one was only audible when directly overhead.
Are they making them quieter these days?

Newer aircraft are quieter. Other factors would come in to play also.

Not a glider,just exceptionally quiet.
I'd guess five or six hundred feet directly overhead and not your normal kind of throaty light aircraft sound,much more heavily silenced.

Wind could have been blowing the sound the operation

Where was this?

maybe he was descending or practicing engine failures/forced landings... but yeah, your modern microlight Rotax/Jabiru engines are much quieter than the old Continental/Lycoming ones.

I was in the garden early one morning(shortly after 4) when an A330 glided overhead at a low altitude tracking the Liffey through the city eastbound. It was super quiet. I suppose it's GE CF6 engines are silent at idle power.
