Over the last four decades of my time flying for a living, I've noticed two things with regard to women flying for theirs.
1. Women can fly if they want to.
2. Most women don't want to.
As a helicopter instructor - and I'm female, BTW - I noticed over the years that it wasn't that women didn't want to fly, but they didn't believe they could. Typically, I'd take a man up for a trial lesson, while his other half watched. Usually, after he came down full of enthusiasm, I'd ask her why she didn't try it. Usual comment, which I heard so often it ceased to surprise me: "Oh no, I couldn't". Not "I don't want to, it's not my thing" but "I couldn't". I'd point out that I'm a perfectly ordinary woman and I did it, so she could too, but it would fall on deaf ears; the woman would usually just repeat like a mantra "Oh no, I couldn't".
Sure, women can fly if they want to. But many don't believe that they can. I doubt if Polly Vacher, or Clare, or me, or anyone else will change attitudes like that very easily. Maybe time will....
