I have to disagree with this. If you can see it, you can hear it. You would feel it in the earth as well. A car crash can be heard for blocks. At least a kilometer. We had a gas main go up and heard it from two miles off on the other side of the village. They were talking of the report of sound from as far away as the next city.
My first thought when I heard something or see something like that is people died today.
I wouldn't have described her as disappointed, but more - cast adrift. The horror she held inside of the plane had to be shared somehow to make it real.. That way it would stop hurting.
Nice story! I see what you are going for, and it just needs a bit of work.
I think that it depends on the size/type of the plane, the distance, and the terrain. Also, determining the actual flight path can be deceptive as the apparent distance can be much further than you think.
Sound also travels at 340 m/s, so something 4 kilometers away would take almost 12 seconds to reach you, if it isn't suppressed by terrain and weather.
We live about 50 km from NASA and some days we hear the launch and it even vibrates the house. Other days you can't. We can certainly see those launches if clouds permit.
A small private plane may not make much of a show if it hit the ground. A 737 would be a different story.
