That thing is so damned noisy! Makes you sympathize with the ravens, doesn’t it?

Being from Maryland, I now have another reason to cheer, “Go ravens!”
I fully agree. All of the promotional videos for autonomous delivery drones and eVTOL vehicles conveniently keep the sound on mute. Can you image the level of noise pollution that would occur if these things followed the normal pattern of development where everyone and his brother needs coffee delivered to them in the morning? The Ravens are doing us a favor.

I only wish the Raven was able to damage the drone enough that it had to make an emergency landing (and that someone nearby would steal it). Those things look (and sound) like a menace.
Absolutely! Can’t make a cup of coffee??? Maybe this guy should get a nurse to spoon feed him.
In fairness, not all are on mute - here’s a recent vid from Lilium Jet covering the approach and landing of their 5th gen demonstrator: youtube.com/watch?v=8FK79N3TWEQ.
Lilium is also the only one that I can recall which stresses their low noise levels (made possible by their ducted fan technology). You really can’t judge noise level from a video, but the nature of the sound - a jet hiss - seems to be far less obnoxious than what you get from open props.
This pleases me. Indeed it’s the best news I’ve heard today.
As a pilot and as a scientist birds fascinate me and I study them. I especially appreciate ravens.
Never have I appreciated them more than now. If anyone ever doubted their superior intelligence hating drones should confirm that they are indeed wonderful birds.
Ravens are really smart. I wonder if one will try dropping pebbles into the fan blades? I don’t know if they have the legal protections enjoyed by hawkd or other birds of prey. Great video. I’m rootin’ for the bird.
Nevermore.
I once had an Osprey take out a small RC “Foamie” I was flying at a park near the water. I was on a small hill and flying a little acro with the plane in the small valley in front of me. Just as I got a battery warning that it was time to land - the Osprey struck from above and shredded the plane. The motor, battery and ESC fell to the ground and the foam fluttered down. Surprised, the Osprey circled a couple of times looking down on the havoc it had wrought and then decided there was probably not much meat to be had and flew off. I spent an hour wandering all over the park picking up foam chips and fragments.
