I've been to Billericay airfield (better known as Chase Farm I believe), it is firmly non-towered.
How about getting away from books, about which there are multiple threads going anyway. Possibilities, some more frivolous than others, might be: -
- Lesson in something totally different (microlight, glider, warbird, helicopter).
- Giant airfix kit for those IMC winter evenings
- Irvin jacket (a bit pointless in a C150 I'll grant you, but they look good)
- Place on a farmstrip course, allowing you to land a C150 at Billericay.
