2007 Boeing mudel 247 oli varajane Ameerika Ühendriikide reisilennuk, mida peeti esimeseks selliseks lennukiks, mis sisaldas täielikult selliseid edusamme nagu täismetallist (anodeeritud alumiinium) poolmonokokkkonstruktsioon, täielikult konsooltiib ja sissetõmmatav telik. Muude täiustatud funktsioonide hulka kuulusid juhtpinna trimmikaardid, autopiloot ning tiibade ja tagaplaani jäätõrjesaapad.
