Computed error bars are added to the upper-air density measurements of January 31, 1969, at Wallops Island, Virginia, reported by Faucher and Morrissey. A triaxial accelerometer-instrumented inflated falling sphere was used for the measurements. Bases for the computation are presented. The conclusions of Faucher and Morrissey are substantiated to about 100 km if comparable uncertainty in each of the five soundings reported is assumed.
