Which aircraft had two advantages over the DC-4 due to being pressurized and faster?

The Constellation, known for its sleek design and advanced technology for its time, had significant advantages over the DC-4, primarily due to its pressurized cabin and higher speed capabilities. The pressurized cabin allowed for more comfortable travel at higher altitudes, reducing fatigue for passengers and crew by maintaining a stable environment despite external changes in atmospheric pressure. This feature was particularly beneficial for long-distance flights, enabling airlines to operate more efficiently and at higher altitudes, where the air is typically smoother.

Additionally, the Constellation was faster than the DC-4, which meant shorter flight times and improved operational efficiency for airlines. These two factors combined to make the Constellation a more advanced choice for commercial aviation compared to its contemporaries, ultimately contributing to its popularity during its operational years.

In contrast, aircraft like the B-52 and the F-100 focus on military applications and do not compare directly to the DC-4's commercial passenger service. The DeHavilland Comet, while also revolutionary due to its design and being one of the first commercial jet airliners, does not match the Constellation in terms of speed and pressurization advantages relative to the DC-4, as it represents a different era in aviation
