Except in a few instances, since World War II no American soldier or sailor has been attacked by enemy air power. Conversely, no enemy soldier orsailor has acted in combat without being attacked or at least threatened by American air power. Aviators have brought the air weapon to bear against enemies while denying them the same prerogative. This is the legacy of the U.S. AirForce, purchased at great cost in both human and material resources.More often than not, aerial pioneers had to fight technological ignorance, bureaucratic opposition, public apathy, and disagreement over purpose.Every step in the evolution of air power led into new and untrodden territory, driven by humanitarian impulses; by the search for higher, faster, and farther flight; or by the conviction that the air way was the best way. Warriors have always coveted the high ground. If technology permitted them to reach it, men, women andan air force held and exploited it-from Thomas Selfridge, first among so many who gave that "last full measure of devotion"; to Women's Airforce Service Pilot Ann Baumgartner, who broke social barriers to become the first Americanwoman to pilot a jet; to Benjamin Davis, who broke racial barriers to become the first African American to command a flying group; to Chuck Yeager, a one-time non-commissioned flight officer who was the first to exceed the speed of sound; to John Levitow, who earned the Medal of Honor by throwing himself over a live flare to save his gunship crew; to John Warden, who began a revolution in air power thought and strategy that was put to spectacular use in the Gulf War.Industrialization has brought total war and air power has brought the means to overfly an enemy's defenses and attack its sources of power directly. Americans have perceived air power from the start as a more efficient means of waging war and as a symbol of the nation's commitment to technology to master challenges, minimize casualties, and defeat adversaries.

The House Rules and Manual contains the fundamental source material for parliamentary procedure used in the House of Representatives: the Constitution of the United States; applicable provisions of Jefferson's Manual; Rules of the House (as of the date of this preface); provisions of law and resolutions having the force of Rules of the House; and pertinent decisions of the Speakers and other presiding officers of the House and Committee of the Whole interpreting the rules and other procedural authority used in the House of Representatives. The rules for the One Hundred Fifteenth Congress were adopted on January 3, 2017, when the House agreed to House Resolution 5. In addition to a series of changes to various standing rules, House Resolution 5 included separate free-standing orders constituting procedures to be followed in the One Hundred Fifteenth Congress. Explanations of the changes to the standing rules appear in the annotations following each rule in the text of this Manual.
