I do have a young family which is a concern I have to admit. In terms of powered flying and from my research it would appear that aircraft such as the ev97 Eurostar, Ikarus 42 or Aquila a211 are the way to go.
I have read that to go solo in a glider costs around £1000 which in comparison to powered flying seems very reasonable. To get a ppl it appears that £10k is about what it would cost then about £150 an hour to hire an aircraft for an hour. No wonder a lot of people simply cannot afford to pursue their dreams of flying!
