Northern Highflyer
Back in the old days when clubs were called "discos", or at a party, if a girl asked what you do and you replied "engineer" the response would be far less favourable than if you answered "unemployed".
I find that most women don't mind too much someone being a pilot but perhaps 75% of them are not interested in flying, and those few that are are only interested in going to interested places, not in flying as such.
I expect it comes from the present-day general public perception of GA being very low, due to the old wreckage they see flying in the skies and at their local airfield.
Apparently, a helicopter gets a better response, although due to the cost of a decent chopper (£500k+) I have not been able to verify this first-hand
The few women who learn to fly seem to be in a different class... but very few of them seem to hang around for long.
