A kilometre is not a unit of area.

C'mon guys, do you mean 60 square kilometres, 60 kilometres square, 60 kilometres radius, or what? Unfortunately, being somewhat literalist, my mental image involves the area being covered by a Peano curve approximation using a strip the width of a road and 60 kilometres long. My mental abilities won't tell me how much area that actually is.

Ah. Thanks.

(My mathematical abilities were somewhat strained yesterday by attempting to calculate the translation vector of the corner of a rectangle undergoing rotation round its centre point. And I was not sure how much to allow for the width of a road.)

Heh, based on the "based on a coverage area of" and "a handful to cover the UK", I'd expect it to be an area approximating that of a square, 60 km to a side.

Having read the article, I'd guess that they mean a circle 60 km in diameter.

Possibly. Or radius, as per one of my guesses. A 60 km radius circle from a high balloon sounds eminently believable to me. The problem is there's a factor of 4 difference between the radius and diameter areas.
