How to solve the final challenge, using Jessica's pieces:
Propeller
- Map of Arles (Arles, 5)/Train (Imire, 7) [the map really points to Lyon, but I'll be generous here]
- Pontoon (Imire, 7)/Scales (Bahrain, 9)
Wings
- Drinking horn (Iceland, 1)/Rope ladder (Antwerp, 2)
- Helmet (Iceland, 1)/Fish (Tangiers, 3)
- Fries (Antwerp, 2)/Elephant (Chiang Mai, 10)
- Fish (Tangiers, 3)/Fortune cookie (San Francisco, 12)
Tail fin
- Magnifying glass (Prague, 6)/Paddle (San Francisco, 12)
- Tyre (Harare, 8 )/Scorpion (Chiang Mai, 10)
Tailplanes
- Helmet (Iceland, 1)/Falcon (Bahrain, 9)
- Rudder (St-Tropez, 4)/Handcuffs (Hong Kong, 11)
- Knight (Arles, 5)/Microphone (Harare, 8 )
- Beer spa (Prague, 6)/Baseball bats (Hong Kong, 11)
1. Even if we didn't know what the rudder was, there isn't anything from St-Tropez. So we assume it's from there and this goes on the plane.
2. The handcuffs take care of Hong Kong, so we eliminate the bats.

3. The only thing left from Prague is the magnifying glass, so this goes on the plane.
4. The paddle takes care of San Francisco, so we eliminate the fortune cookie.

5. The only thing left from Tangiers is the fish, so this goes on the plane.
6. The helmet takes care of Iceland, so we eliminate the drinking horn and the other helmet.
7. The only thing left from Bahrain are the scales, so this goes on the plane.
