From canvas tents to Terminal 6 charting the history of Heathrow Airport in photographs. London's Heathrow Airport has seen dramatic changes since it opened in 1946, from canvas tents as terminal buildings serving converted military piston-engined airliners to the latest Airbus and Boeing jet airliners operating from five modern sophisticated terminals. As air travel became more affordable, Heathrow has expanded to accommodate the increase in airline traffic. This pictorial timeline records these changes in air transport and infrastructure to capture the interest of the aviation enthusiast, the Heathrow visitor or just someone who is fascinated by nostalgia in an ever-changing world.
