Re pilotmike post #2001, quote from Wiki:
"...the biplane was similar to Lady Heath's in size and design..."
I think it needs to be said here, for the benefit of readers who may not (yet) be aviation anoraks, that the statement is misleading.
The Stearman first flew in the mid-1930s, whereas Lady Heath flew her Avro Avian from Cape Town to England (Croydon) in 1928.
While the wingspan and fuselage-length of the Stearman are only slightly greater than Heath's Avro Avian and Amy Johnson's DH Gypsy Moth, the Stearman is a far more robust and powerful machine. Its loaded weight is about twice that of either, and its original versions had well over twice the power of Heath's 84 horse-power Avian. Ms Curtis-Taylor's aircraft has over three times the power.
