Scroggs is quite correct, over the years I have seen no difference in the abilities of either sex when it comes to operating aircraft. It is not a skill that requires physical strength, only reasonable hand/eye co-ordination, the ability to think ahead and good situational awareness. Flying is not a difficult discipline and can be learned by most people, as can the operation of most transport machinery eg; cars, motor-bikes etc.
To be gifted, or excellent is not required for normal commercial operation, this is an ability reserved for aerobatic champions, front line fighter-pilots, grand-prix motorcyclists and formula 1 racing-drivers.
The majority of people can be trained to fly to the required standard for public transport work there is no mystery, flying airliners is not difficult. However, take heart ladies, if two equally qualified persons apply for the same position,current practise[not policy] favours your goodselves.
Cheers.
