The Waterman (W. D.) 1932 B Whatsit (X12272) was a tailless airplane designed by Waldo Waterman to be as easy for the average person to fly as it was to drive an automobile. Paul R. Matt was a draftsman and acquaintance of Waldo Waterman who contacted the National Air Museum in 1964 and offered to produce drawings of the Waterman (W. D.) 1932 B Whatsit (X12272) and Waterman (Arrowplane) Arrowbile Prototype (X262Y) with Waterman's input and approval. This collection consists of two three-view drawings of the Waterman (W. D.) 1932 B Whatsit (X12272) by Paul R. Matt.

The Waterman (W. D.) 1932 B Whatsit (X12272) was a tailless airplane designed by Waldo Waterman to be as easy for the average person to fly as it was to drive an automobile. The Whatsit was first flown in July 1932 and early flights showed problems with pitch stability and landing accidents so Waterman set the project aside. In 1933, Eugene Vidal, Chief of the US Bureau of Air Commerce, issued a challenge to US aircraft manufacturers to design and build a safe and inexpensive airplane for the average person. Waterman reviewed the specifications in the challenge and realized they closely followed his work on the Whatsit. Waterman made improvements and redesigned the aircraft and the result was the Waterman (Arrowplane) Arrowbile Prototype (X262Y), which was delivered to the Bureau of Air Commerce in July 1935. The Arrowbile was one of two winners of the challenge. The Whatsit (X12272) was a player in the development of the tailless flying wing concept and was a major contributor in the reestablishment of the steerable nose wheel for the tricycle landing gear utilized in many modern airplane designs. Following its useful test life, the Whatsit was stored by Waterman in anticipation of donating the aircraft to the Smithsonian, where it arrived at the National Air Museum in 1950. Paul R. Matt was a draftsman and acquaintance of Waldo Waterman who contacted the National Air Museum in 1964 and offered to produce drawings of the Waterman (W. D.) 1932 B Whatsit (X12272) and Waterman (Arrowplane) Arrowbile Prototype (X262Y) with Waterman's input and approval. Terms were agreed upon and the final drawings were delivered to the Museum in April 1965.
