Douglas C-4X Heavy Airlifter (for Mostly’s competition)

While it closely resembles a C-5, this is NOT a replica, but rather a cargo plane based off of the various designs Doulgas (and boeing) submitted for the CX-HLS competition (which the C-5 won). It also retains the MATS livery that was common on 60s airlifters.
This particular aircraft is perfect for any use, whether that be transporting large cargo or using it as a SSTO launch vehicle, with its <800 ton carrying capacity, the possibilities are virtually endless.

Specs:
Max Speed: 427 knots (211 m/s)
Never exceed Speed: 215-230 m/s
Service ceiling: 36k ft

Controls:
Slider 1: flaps
Others are labeled (use slider 2 for doors + ramp)

Notes:
Do not go over the never exceed speed or wings will implode
Do not bank at a angle greater than 60’ or wings will implode (again)
Dont be stupid and open the nose mid-flight or the aircraft will go into a spin and wings go boom boom

Reflection:
I feel guilty for submitting this so late, and I really owe it to Mostly. For my first aircraft (from scratch) I think I did well. A lot of effort was put into this, and it would be a dream to see this upvoted.
