And yet this video that people claim is the Chinese launching a missile shows the missile going up into a ballistic trajectory and not the flatter trajectory that your scenario would require.
Ground observers won’t even see the tip over point for a depressed trajectory it’s at 500,000+ feet up well above the atmosphere.
Figure 2 shows a DP vs ballistic over a 1000nm mile path the scale should be obvious. For longer DP lengths the tip over point is still higher. A DP is still a Newtonian physics governed trajectory there is no lift generated from the atmosphere it is a trajectory that has enough excess speed relative to gravitational vector to arc upwards. Put another way a DP is a sub orbital trajectory with it’s V vector sub parallel to the earth’s surface.
