2. It is the world's first combat glider.

The Harrier Jump Jet was developed to take off and land in small spaces, without a long runway.

1. A heavily modified Dodge Hemi

The idea of powering the XB-70 with a nuclear reactor was abandoned when it became clear how costly and potentially disastrous it would be.

1. C-5 Galaxy
   Antonov An-225 Mriya
2. C-17 Globemaster III

The An-225 is larger and heavier than any other plane in the world. Only one was built, although it's currently in commercial service and no longer a military plane. It is almost six stories tall.

1. De Havilland Hornet
   Supermarine Spitfire

1. P-36 Hawk
   P-38 Lightning
2. P-66 Vanguard

The P-38's twin tails gave it very stable aerodynamics, but it was not the most agile plane. It excelled as a heavy fighter and in fighter/bomber missions.

1. Russia
   Britain
2. China

The Yakovlev Yak-3 was a small, light but extremely agile fighter deployed by Soviet forces in World War II.

1. The Flying Tigers
   The Spooky Squadron
2. The Devilfish

The Flying Tigers were a volunteer group of U.S. pilots that fought in China against Japan. The shark mouth insignia on their airplanes was (and still is) the most iconic nose art in the world.

1. Enola Gay
   Hellfire Special
2. Jenny Come Home

The pilot named the Enola Gay for his mother, Enola Gay Tibbets. The airplane is on display at the Smithsonian's National Air and Space Museum annex at Dulles International Airport.

1. B-24 Liberator
   B-25 Mitchell
2. B-17 Flying Fortress

Ones of the B-17s used in the movie is still flown today with the Memphis Belle name. The real Memphis Belle that inspired the movie is now on display at the National Museum of the United States Airforce.

1. Heavy transport
   Attack helicopter
2. Scouting and observation

With its 30 mm chain gun and Hellfire missiles, the Apache is a formidable attack helicopter.

1. The American Civil War
   The War of 1812
2. The Franco-Prussian War

The Union had a balloon corps that performed mapping and observation duties in the Civil War.

1. Windows
   A tail rudder
2. An engine

The Waco was a combat glider, towed behind a C-47. It had no engine of its own.

1. Smokey
   Turkey Vulture
2. Warthog

Its ungainly appearance earned the A-10 the Warthog nickname. There were 716 of these built, and they're still in use today.

1. More than 12,000
   About 25,000
2. More than 36,000

The Soviets put over 36,000 Sturmoviks in the air during the war. They are a type of ground-attack aircraft.

1. A submarine-launched rocket plane
   A prototype space-plane that could have bombed U.S. cities
2. The world's first operational jet-powered flying wing

The Ho 229 was a flying wing, a plane with no fuselage. Only three of them were ever built and used by the Luftwaffe.

1. Messerschmitt Me 262
   Focke-Wulf Fw 190
2. Kawasaki Ki-100 Goshikisen

The Messerschmitt Me 262 was probably the most advanced plane of World War II, but because it was an example of a piece of cutting edge of technology, that made it complicated and difficult to maintain.

1. Italy
   Germany
2. Japan

Allied forces developed codenames for Japanese aircraft because the Japanese designations were complicated and hard to differentiate. The official codename for the Zero was Zeke.

1. Gloster Meteor
   P-51 Mustang
2. Curtiss Helldiver

Nearly 4,000 Gloster Meteors were built, entering service in 1944. They were officially retired in the 1980s, after serving a second life as Royal Air Force target tugs.

1. The Boer War
   World War I
2. World War II

When Snoopy pretends to be a World War I flying ace, he flies an imaginary Sopwith Camel.

1. Johann Mueller, the Iron Duke
   Manfred von Richthofen, the Red Baron
2. Karl Lindmarst, the Berlin Butcher

Manfred von Richthofen flew several different types of aircraft during World War I, but the distinctive look of the Dr.I's three wings made it more notorious than the others.

1. Smart bomb technology
   Stealth technology
2. Ultra-long range technology

Stealth aircraft are designed to have radar signatures far smaller than their actual size and to diffuse and mask the thermal output of the engines.

1. Sukhoi PAK FA
   F-117 Nighthawk
2. A-12 Avenger

The F-117 Nighthawk first saw action in Panama in 1989. As of 2016, the U.S. is the only nation to have used stealth aircraft in combat.

1. Extremely low radar signature
   Ultra-long range fuel efficiency
2. The ability to fly to the upper edge of the atmosphere

Stealth technology wasn't really a consideration when the Vulcan was designed in the 1950s, but its sleek design with enclosed engines and a low-profile fuselage made it more difficult to detect on radar than almost any other aircraft of its era.

1. F-20 Tigershark
   F-15 Strike Eagle
2. F-14 Tomcat

Goose, Maverick and Iceman flew F-14 Tomcats. Over 700 of them were built.

1. Hangtime
   Huey
2. Bulldog

Hueys played a number of roles in Vietnam, including assault missions and medical evacuation of troops.

1. F-15 Strike Eagle
   F-22 Raptor
2. AV-8B Harrier II

The F-22 Raptor was literally too good. The more versatile F-35 will be the primary fighter for the U.S. military instead in the coming decades.

1. EU-77 Citadel
   IG-4 EuroJet
2. Eurofighter Typhoon

The Eurofighter Typhoon was designed and built via a multi-nation effort. Several Middle Eastern nations are also using it.

1. B-58 Hustler and Yak-28
   F-111B and Tu-28
2. F-4 Phantom II and MiG-21

F-4 Phantom IIs and MiG-21s engaged in many duels in the skies above Vietnam. The U.S. ended their involvement with the war in 1973.
