Planes in KSP usually weight a lot. Sadly the Kerbal goverment noticed that runways started to break due to the immense weight of the planes. He called up Wernher von Kerman and asked him to come up with a solution. The president expected a reinforcement method for the runways. He was wrong though and Wernher proposed new guidelines for aircraft. The president looked through them and was satisfied, making it a law.
The guidelines (rules for the challenge) were:
A plane must weigh under a ton without kerbals & fuel.
A plane must be able to carry atleast 2 kerbals.
A plane may only be powered by jet engines to not waste precious oxidizer.
A plane is not allowed to use custom parts (modded parts) and must stick with them provided by the Kerbal Space Center (stock parts)
A plane shall be flying with lift and not be a metal tube with a couple of chairs and an engine.
A plane shall be able to fly to the Old Airfield.
A plane shall not be using any mad tricks (Alt + F12 cheats)
To calculate score:
1000* Number of Kerbals aboard / (Weight in tonnes * Time from take-off to land on the Old Airfield Runway in seconds)
1. @foamyesque Score: 16.7
2. @Cunjo Carl Score: 12.80
3. @zolotiyeruki Score: 11.44
4. @Jetski Score: 10.75
5. @Panel Score: 7.74
(By the way, should I make a badge for this?)
