The flying cars were one of S.H.I.E.L.D.'s many weapons.
The flying cars were used by S.H.I.E.L.D. agents. The S.H.I.E.L.D. cars at first looked like normal vehicles. However, by pressing a button inside the car it would transform into a jet plane that the S.H.I.E.L.D. agents would use to get from place to place.
- In the comics the S.H.I.E.L.D. flying cars were created by Stark Enterprises.
- In Spider-Man: The Animated Series the cars transformed into a jet plane. This differed from the comics because in the comics the car did not transform into a plane. Instead the wheels of the car would rotate to where the hubcap would face the ground and the hubcaps would release a jet propulsion that would cause the car to hover above the ground and fly.
