I hear them daily.
It would be amusing to see his head tilt when he saw a UH-1Y and it wasn't making the pop sound.
When the Bushes were in office we heard some kind of choppers heading up to the summer residence every few months. They flew way up there and unless one was outside seldom heard them.
The ones we hear inside a building are either Police or private choppers doing Aeriell photography or surveying the area. These fly close to the ground and make a racket of noise.
Only been up ONCE on a tour of NYC back in 1969. Darnedest feeling, the machine had a bubble glass front and seats for 3. The chopper did not leave the earth, if felt like the earth was sinking below me, flight restrictions at the time many buildings were higher then we were. Pure magic for me, so different from a small private plane.
Our small town airport has in good weather all kinds of gizmo's flying just above tree top, ultra lights and home made in the garage contraptions with Snow Machine engines or water ski engines for propelsion. Now this is scary. Some of these pilots fly so low one cannot sunbath nude on their decks. { yes I know that would be a sight to make them crash into the neighbors house. }
I would be more afraid of a neighbors who builds these things and their teenage kid on drugs decides to buzz the block then any Military chopper.
This poster sounds like Nads who when hearing an ambulance has a flash back to repelling down 150 feet in a lightning storm to take vitals of dead people.
