### Clue: Flyer follows boat to take off (8)
### Answer: SUBTRACT 
 ### Explanation: Definition: to take off 
**TRACT** ("flyer" as in piece of paper) *follows ***SUB **("boat") 
*At first, I thought "boat" was a bit weak and thought "ship" may have been a bit better, but subs are also known as U-boats, so it's probably fine.
