The sheer size of the Saturn V is pretty amazing. Already almost 40 years retired, the Saturn V was designed to lift 200 tons into low earth orbit.

The Cheapest Time To Buy Airline Tickets

The Observer points out that economist Makoto Watanabe has determined, using the formula ∏A = gUG + min(k – g, (1 – g)(1 – r)), that the best time to buy airline tickets is at noon, eight weeks before flying.

An economist, Makoto Watanabe, has calculated that the optimum time to buy an airline ticket is eight weeks in advance of flying. His yet-to-be-published findings also suggests that airline tickets are cheaper when purchased in the afternoons, rather than the mornings, prompting him to speculate that airlines are assuming business travellers will book their tickets at work in the morning on the company account, whereas leisure travellers are more likely to book from home in the afternoon.

Maps Of City Skylines

A few weeks ago, Eric Fischer put together a set of maps that attempted to compare the areas of a city that were most often photographed by locals versus the areas most often photographed by tourists. A look through the maps of 60 different cities shows concentrations of web-posted tourist pictures in museums, parks, historic sites, architectural marvels, etc. Other (more) interesting areas of the city are filled in by photographs from the locals.

Another cartography tool to add to your travel-photography-belt are Andy Woodruff’s maps depicting the best areas to photograph a city’s skyline (as defined by photos tagged “skyline” on Flickr). They were put together in a sort of heat map style where brighter red and yellow marks indicate a higher density of photos (and presumably a superior view of the skyline). His blog has maps of several cities, including Boston, Seattle, Vancouver, and Chicago, among others.

Unfortunately, neither Eric’s tourists maps nor Andy’s skyline maps contain locations in Denver.
