Has a date of July 1st 2019 so not sure if this is old news or not. Anyways some reading material for those that have not seen it yet.

Assessing the danger of drone strike: unique test bench to measure collision impact

Avoid taking aluminum plates while flying, drones do not like them.

“847,000 in private and commercial use, in Germany, by 2030.”

1) How many of those are being purchased today and expected to still be in service in 11 years?

2) of those 847,000 UAS, how many will actually be in flight at the same time?

I have seven if I count my Hubsans. [emoji41]. Ok, four that actually see the skies and of those, only one at a time.

I’m not in Germany, but the same rebuttal applies every time we see these predictions of doom and gloom.

Oh, and flying near manned aircraft - never.

Anyone fail to see my point?

Not sure what happened to the page. Perhaps I screwed up, darn thats the second time in 62 years. I need to rethink things I guess

From a “public outlet” perspective it should be considered new as the story just hit main stream media today.

I haven't found any drones weighing 3 kg that fly at 150, 115.....110 meters a second.....45 mph equals 66 ft per second.....German ignorance

But the drone and the plane might get to that? 2 moving objects.

It’s not the speed of the drone that makes speed a factor, unless it’s a drone that can fly at 50-80-100 knots. It’s the speed of the full scale.

If anyone wants to test that out just stand in front of a car moving 100+ miles an hour. If you’re standing still you will experience the effects of a 100 mph collision with a solid object. If you are moving 20mph the kinetic energy will equal a 120mph collision.

So a full scale moving at whatever speed impacting even a motionless drone will experience kinetic impact energy equal to the speed it is moving at. The physics were established a long time ago; energy = mass x velocity2.

It was told in road safety adverts, it's the combined speed and you could die even if both vehicles were going 15mph, it was x2 so a 30mph crash.
