This comic is pointing out that more time has elapsed since the first spaceship flight, than previously elapsed between the first airplane flight and the first spaceship flight.
Airplanes and spaceships are often considered to be related vehicles, under the term aerospace, with degrees in aerospace fields often having aeronautics (airplanes) or astronautics (spaceships) tracks. The jump in technology and performance between the first airplane and the first spaceship was enormous: the Wright Flyer had a max speed of 30 mph, and the first flights reached only about 30 feet above ground, with distances of only 120 to 850 feet. In comparison the Vostok 1 mission of Yuri Gagarin reached orbital velocity of 17,500 mph, a minimum altitude of 91 miles (480,480 feet), and traveled once around the earth (about 25,000 miles). This represents an increase in performance of between about 600 and 150,000 times.
By contrast, an equal amount of time has passed between the first spaceflight and the publish date of this comic, but aeronautical performance has not improved much at all. Although the Apollo mission broke speed and altitude records, and later space missions extended the distance traveled in a single flight by sustaining Earth orbit for longer, the overall technology and performance is not much different that that used during the first space mission.
The title text refers to the 2003 film The Core. In this film, there is an instability in the Earth's magnetic field, so a team of scientists attempt to drill to the center of the Earth and set off nuclear explosions to restart the rotation of the Earth's core. To do this, they travel in a vehicle made of "Unobtainium" that can withstand the heat and pressure within the Earth's crust. Randall is sad to report that there is little progress being made on creating this vehicle. Incidentally, The Core is a film which represents science and engineering wrong in many, many aspects. There is a long list of flaws; for instance, if a material is resistant to the extreme heat and pressure of the Earth's core, then the significantly cooler and less forceful techniques of human metallurgy would certainly not be able to work that material at all, let alone craft it into a functional hull for a vehicle.
