McDonnell Douglas was a titan of American aerospace, a company whose aircraft defined the skyline for decades with their distinctive T-tails and rear-mounted engines. Known for their rugged construction and pilot-centric designs, "MD" aircraft, from the classic DC-9 and its evolutionary MD-80/90 successors to the large DC-10 and MD-11 tri-jets, were the workhorses of the world's major airlines. Though the company eventually merged with Boeing, the legacy of the "Mad Dog" and the majestic triple-engine MD-11 lives on. These aircraft are celebrated for their unique character, impressive performance, and the crucial role they played in expanding global air travel during the late 20th century.
