As we mark the centennial of the U.S. entry into the first World War — the first war fought in the skies as well as on the ground — we've found some of the best places for you to see the planes involved in the conflict.

Whether you're an aviation geek or a history buff (or both), you'll enjoy a time travel journey in these museums of flight.

Visit the Royal Museum of the Armed Forces and Military History in Brussels. It has one of the world's largest collections of First World War artefacts in a permanent exhibit which sheds light on the heartbreaking realities for those fighting the 'war to end all wars'. You'll find an impressive collection of WWI biplanes in the Aviation Hall (as well as an impressive collection of WWII planes) in its massive hangar.

Head over to London and plan a few extra days to make your way through the RAF Museums. The Grahame-White Factory and Watch-Office has a permanent exhibition: “The First World War in the Air.” It features aircraft, uniforms, personal letters and other memorabilia which will give you a true appreciation for the men fighting in the battlefront of the clouds.

If you love all things aviation and aerospace, you can never go wrong with a visit to the Smithsonian's National Air and Space Museum. The Museum is marking the centennial of the United States' entry into first world war with a series of exhibits and films. The Legend, Memory and the Great War in the Air exhibition includes a prized collection of rare WWI aircraft and memorabilia, as well as special screenings of vintage WWI films. Don't forget to stop by the WWI Artist Soldiers exhibition for a unique view on the personal experience of those engaged in the conflict. You can plan ahead by downloading the Museum's app for Apple or Android.

The Museum of Flight in Seattle also features WWI aircraft, interactive exhibits about the war in the skies, as well as an enviable collection of over 150 detailed 1/48 scale models of WWI planes — and a 13 1/2 foot long model Zeppelin.
