...been left most of Cissie's personal effects, some real estate, and an income of $25,000 a year for life.

...speed of the dive increased, the machometer needle crept up to Mach 1, the speed of sound. Then it went on up to Mach 1.1. The controls felt heavy, but nothing really unpleasant happened.

His top speed was probably just under 700 m.p.h...
