For "dual" read not solo.
There is so much hair splitting that it's impossible to keep up!
The HCAP award says in part,
Tracey's team consisting her co-pilot and engineer, Ewald Gritsch
Yet to repeat what Ewald says,
“But I did NOT act as a pilot nor as a flight instructor on these expedition flights”
So which is it? Co-pilot, or not? Nothing hair splitting about it at all. Either way, someone is being economical with the truth.
