Spider-Man 042a - Sky Harbour

The Nazi Baron Von Rantenraven has developed Sky Harbor, a mobile aerial platform capable of launching attacks from anywhere. They have been working on this in secret since World War I and are now ready to show the world what they have made.
Rantenraven leads an attack of the vintage German biplanes against a commercial airliner. They drop their "dispersion dust" on it, causing it to stall in mid-air. They capture the plane and return it to Sky Harbor.
This creates an international incident. Rantenraven demands that the U.N. grant him complete control of the skies. Due to the hostages, military action is not an option. While the mayor and his military advisor confer on what to do, Spider-Man volunteers to stop Rantenraven.
