World War I

The first Zuiderzee Enclosure Dam ran from North Holland to the island of Wieringen, successfully barring the sea for over 50 years and protecting a large area north of Amsterdam. The total Zuiderzee project was the largest land reclamation effort in the Netherlands, developed over a period of about 80 years, beginning in 1918 and reaching completion in 1996. The huge dyke/dam was considered one of the greatest engineering feats of its time.

Although not the first four-wheel-drive vehicle or the first designed for rough, multipurpose field use, the Jeep MB was built as an unusual combination of these and other features of modern vehicle design in the World War II era.

In its infancy, Hangar Nine housed Curtiss JN-4s ("Jennys") like the one Charles Lindbergh landed there when he reported for duty as a flying cadet in 1924.

As the U.S. was preparing to enter World War I, the Army raced to build an entire airfield, complete with 16 wooden hangars, successfully completing it in less than a year. The last remaining World War I facility of its kind, Hangar Nine at Brooks Air Force Base represents the emergence of fast-track construction methods using available materials and the skills of a local workforce.
