How many hours did you fly last year?

Pretty difficult to fly hours. You can fly an airplane, a ballon, a kite
etc. but you can't fly an hour.

How many hours did you spend flying last year would be the literate way to
ask the question.


Bzzzzzt. Sorry, not so.

I spent hundreds of hours flying last year. A few of them in my aircraft, a
lot of them in the torch.

However, the first question is grammatically correct. Asking how many hours
**I** flew last year implies that **I** flew them, not that I was flown.
