* The missile (with booster) was launched 0.4 seconds ago, and is accelerating to mach 3.4 (25 times the force of earth's gravity), has risen 60 feet, and is now going 210 miles per hour.
In four seconds from now the missile will be 100,000 feet away from a launch angle between 85 and 89 degrees (NOT AT 90 DEGREES)
Going 1,700 miles per hour
Separating from the booster
Turning (diving) towards the intercept point to the target
At booster separation the sustainer motor / rocket engine starts to reach 2,700 miles per hour.
If the target is 90 miles approaching at mach 3.5, the missile will meet the target 60 miles away in 90 seconds
