Based on the Apollo lunar landing experience, errors are apparent in the cover picture. The hatch would not exist in the rear of the rocket where fuel tanks are best positioned. Additionally, there seems to be no hinged door for sealing the opening from which the servicing team egresses from the spaceship. Two of the repair crew are tethered to the vehicle, but the crewman emerging from the vehicle has no tether. How will he transfer the repair plates to the torch wielding repairman? Note the pair of round disks on the soles of each spaceboot. The concept of magnetic grapplers to fasten astronauts to space structures never developed in actual practice.
