Hollow Earth Aerial Vehicle

The Hollow Earth Aerial Vehicle (H.E.A.V.) is a vehicle created to explore the Hollow Earth that appeared in Godzilla vs. Kong.

Appearance
The H.E.A.V. is an air vehicle with 4 mobile turbines that emit an unknown energy that allow it to float and manipulate the gravity around it. The entrance to the H.E.A.V. is located at the rear. Its door opens outward, creating a ramp so that it is possible to enter. At the front of the craft under the nose is what appears to be a small spherical sensor array of some sort.

Godzilla vs. Kong
The H.E.A.V. were prototype anti-gravity vehicles created by Apex Cybernetics based on the technology used in Apex's transport network to move large amount of materials between various branches. They were specifically designed to be able to resist the massive and violent gravitational reversal effects typically found on the paths down into the Hollow Earth, and were powered by an unknown power source capable of "lighting up the whole of Las Vegas for a week." To protect the occupants from any possible Titan threats encountered on the expedition, the vehicles were equipped with missile launchers and twin machine-guns. Three were deployed with the goal to follow Kong down into the Hollow Earth in an attempt to locate the primeval energy source believed to be down there. In the course of the expedition one was destroyed by a Warbat, a second one was crushed by Kong after Apex executive Maia Simmons ordered the pilot to fire on Kong, and the final one was sacrificed to restart Kong's heart after he was nearly killed fighting Godzilla.
