AFJROTC Commercial and General Aviation Take Off Practice Exam

Which aircraft was known as the "Seven Seas" because of its great range?

1. DC-3

2. Boeing 747

3. DC-7C

4. Lockheed L-1011

The correct answer is: DC-7C

The DC-7C is referred to as the "Seven Seas" due to its exceptional long-range capabilities, making it one of the first aircraft to have the operational range to serve transcontinental and even transoceanic routes effectively. It was specifically designed for long-distance travel and exceeded the range of many earlier commercial aircraft, allowing airlines to connect distant locations without the need for intermediate stops. This capability made it particularly well-suited for the burgeoning global travel market in the mid-20th century. In contrast, while the DC-3 and Boeing 747 also had significant ranges, they were not specifically labeled as the "Seven Seas." The DC-3, being a smaller and older aircraft, was mainly used for shorter routes in its heyday. The Boeing 747 is known for its capacity and versatility but debuted later and was not associated with that title. The Lockheed L-1011, although a remarkable aircraft in its own right, also does not carry the "Seven Seas" moniker. Therefore, the DC-7C stands out as the aircraft associated with this nickname, highlighting its role in aviation history as a pioneer in long-range commercial travel.
