After failing to design a heavy passenger airplane for a third party contract, the heads of WinterTech discovered that they owned a patent of a heavy cargo plane from a bankrupt startup they had purchased. After "accidentally" installing seats on the cargo bays and presenting it as brand new, it became a huge sensation in the industry. Reports of traces of glue found near the edges of the fuselages are exaggerated according to WinderTech’s CEO.
Truly a behemoth of its own kind, the Humpback is one of the few airliners utilizing a complete second fuselage design, as well as a secondary cockpit. Eight Nine of the most efficient turbofans provide generous thrust at low altitudes and speeds. Despite its humongous mass it can takeoff really easily by starting yaw control at 70m/s and it can climb up at angles as steep as 30 degrees. It cruises well at a speed of 200m/s and an altitude of 4,5km, but it can rise up to 6km when at the final third of its fuel. With its fuel tanks filled to the brim, it can easily circumnavigate the entire globe without refueling with an acceptable TWR, but the fuel levels should be adjusted for shorter journeys. It has a capacity of 134 Kerbals or 192 "Kerbal Passengers" according to the rules of the challenge.
Its passenger capacity could easily be increased to ~220 with no more than 50.000 extra, but this would ruin the beautiful symmetric appearance of the plane
It is true that the price tag of the aircraft is pretty high, mostly as a result of tension between C7 and WinterTech causing an increase in the price of the C7 Mk3 passenger bays (30k? Really?). Only a fraction of the cost is the fuel, so an investment in this plane will pay off quickly. We hope that better diplomacy and cooperation between the companies will result in the price being reduced in the future.
