no rocket flies perfectly vertical. the barometer reading is the real
apogee, the accelerometer reading is the distance traveled to apogee.
imagine a triangle, one point at the launch site, the hypotenuse is the
accel, the long side of triangle is the baro; so the short side of the
triangle is the radial distance from the launch point.
so Pythagoras says Shikra flew 85.4 degrees! pretty darn excellent!
