The Stearman is not even fully dual.
A characteristically snakey thing for her to say.
When she's dun slitherin', the fact remains that the owner's suite in the front office had stick and rudder and throttle controls.
Most importantly of all, it had an intercomm, through which the five-figure-hour experienced ATPL/QFI could talk to her_in_back and walk her through the more complicated bits of following the magenta line of her (and his) GPS-equipped iPads. Y'know, stuff like turn left or turn right or level the wings or tread on the ball, that sort of stuff.
Not quite comparable to Amy Johnson or Mary Heath or the Honourable Mrs Victor Mildred Wossername.
