This time, Rocket folds slowly. Raven lines up each edge.
Both wings match. Rocket stands behind the same line.
Whoosh! The plane glides straight and smooth.
Nova zooms to the landing spot. "Twelve feet!"
Rocket and Raven do a happy dance.
| Version | Throw 1 | Throw 2 | Throw 3 | Past 10 feet? |
|---|---|---|---|---|
| Rocket version 1 | 4 feet | 5 feet | 4 feet | No |
| Rocket version 2 | 11 feet | 12 feet | 9 feet | Yes |
Version 2 flew much farther.
But one throw only went 9 feet.
Honest engineers write down every throw, even the short ones.
The best throw went past 10 feet, so the goal is met.
