Sergey Brin, co-founder of Google, is funding the construction of a secret airship at NASA Ames in Mountain View, California, through his company Lighter Than Air (LTA). The airship, called the Pathfinder One, is 122 meters long and has a total lift of 28 tons, with a maximum speed of 60 knots and a range of over 2,000 nautical miles. LTA’s mission is to use lighter-than-air technology for humanitarian relief and reduce the carbon footprint of aviation. The company plans to build larger airships that can carry up to 200 tons of cargo and is working towards making airships a viable mode of transportation. Despite the challenges and risks associated with airships, LTA’s CEO Al Weston remains optimistic about their potential and envisions a future where airships are mass-produced and widely used.

One of the most interesting grammar points in this text is the use of the present perfect continuous tense to talk about an action that started in the past and has continued up to the present moment, often to show the result of that action. For example:
- I’ve been really intrigued about the question, can these airships be made quickly and affordably enough to be mass produced?
- I’ve known for years who really gets around Silicon Valley.
- They’ve studied airships that could carry up to 200 tons of cargo.
This tense is often used to talk about an action that has been in progress for a certain amount of time, and is still continuing. It can also be used to show the result of an action, as in the first example above.
Here are five multiple-choice questions to practice the present perfect continuous tense:
