1. By Molly and Aleina Ours is the best (boom)

2.  Four forces  Propulsion  Lift  Fuselage

3.  Most go 500 miles  Most hold 80 or more people  Must not use a runway  Must cost $76,000,000 or less  Must not use a runway The situation we choose The situation we choose was long haul. We are on a sports team at our school and we made it to the national championships. We have $76,000,000 to spend on our air craft. The rotors allow it to have no runway.

4. GOOD  BAD   The plane will not have a lot of downwash  Less noise  Less fuel efficiency  We choose the stuff that costs the most  The body was heavy

5. We choose the 8 rotor lift system because it dose not have a lot of downwash.

6. We choose engine one because it has more power and scene it has more power it works good,because are suppose to carry 81 people.

7. We choose her because she not only builds airplanes she is a pilot too.

8. We choose fuselage number 3. We choose it because it can hold more than 80 people.

9. Four forces The four forces work together to make our plane move because drag makes it go backwards.Thrust makes it go forward. Lift pushes it up. Weight pushes it down.

10. beginningending  Smaller  No propeller  rockets  Bigger  Propeller  No rockets

11.  Flew great  Right distant  Perfect time
