I just finished watching the first season of Wings. It is a 1977-78 BBC produced series focused on a British 17 year old who wants to fly in the Royal Flying Corps in 1915. His family are involved in a smithery. I stumbled upon this series while doing research on the British B.E. 2c aircraft. It turns out this plane is basically the only British plane featured, but the plane and action looked great in the episodes.
A blog I read recommended watching the series, so I started watching it. Each episode is about 47 minutes. It is completely available on YouTube. Each episode spends about half the time featuring events with his family or love interest at home and the other half with his squadron. I also recommend watching this series. I was pleasantly surprised. The blog that recommended it also recommended not watching the second season, so I'll pass on that.
I actually recognized some of the actors in the series. I think the one that stands out the most is Michael Cochrane. I watched him play a General in the Sir Henry Simmerson in the BBC Sharpe Series. You can't miss him in Wings. Just a wee bit younger.
