A cruise missile, small--say 10 feet long, making 4000 mph at 1 mile altitude-
Would it make a boom loud enough to break windows? The smaller the craft, the less the boom, correct? Probably would be a tough one to answer; no aircraft I'm aware of is that small, making that kind of speed.
The X-15 could do Mach 6, but at what, 20 miles up. Any ideas about what the skin of a craft built for low altitudes could be made of? Something made of the same material as the shuttles tiles?
At that speed and low, one mile altitude, would the air be ionized and the skin glow? How would it appear from the ground, in other words?
Also how fast is mach 10?

The speed of Mach 10 is ten times the speed of sound, which is approximately 7,660 miles per hour (12,345 kilometers per hour) at sea level and room temperature (about 68°F or 20°C). Therefore, Mach 10 is:
Mach 10 = 10 times the speed of soundMach 10 ≈ 76,600 miles per hour (123,450 kilometers per hour)
It's important to note that the speed of sound varies with factors like altitude and air temperature, so the specific speed of Mach 10 may differ slightly depending on these conditions. This calculation provides a rough estimate for typical conditions at sea level.
