>Bill,

There is a generally accepted reference altitude for atmospheric
reentry: 122 km (reentry interface).Breakup appears normally between 85
- 70 km altitude, depending mainly from the mass of the object.
There are different altitudes in use for given geographic
decay or "impact" coordinates: SPACECOM'S and my own issued
data have a "final" geodetic altitude of 10 km on the reentry
trajectory. Other groups use 65 km or the begin of the vertical
fall.
