DIA turns 25: Here's all of our coverage

Feb. 28 is Denver International Airport's 25th . We're taking a look at the past, present and future of this Mile High City icon.

DENVER — Denver International Airport is finally old enough to rent a car.

While it might be tough to imagine life in Denver before DIA, it’s actually one of the newest airports in the country. On Feb. 28, 1995, it replaced the aging Stapleton International Airport, paving the way for a new chapter in the Mile High City’s history.

In the years since, DIA has gotten a new hotel as well as a train connecting it to Union Station 25 miles away. When it opened, it was $2 billion over-budget, and “ridiculed by detractors as a $4.9 billion monument to boosterism and boondoggling.”

Today, the airport is still mired in some controversy. A project aimed at renovating the Great Hall is also way behind schedule and also overbudget. But along the way, its also been lauded for helping to spark the city’s growth.

The land is 53 square miles — making DIA bigger than the island of Manhattan. In fact, in terms of area owned by the airport, DIA is the second-largest in the world (behind King Fahd in Saudi Arabia).

But what about the tunnels?

Two Lizard People point at the Illuminati logo near their headquarters, Denver International Airport (if you don't get this is a joke, I can't help you).

Since it opened, DIA has been mired with conspiracy theories. After all, its mascot is a blue horse with laser eyes, and does it really need all those tunnels? 

The answer to the second question, at least according to the airport, is yes. But, is that just what DIA wants you to think?!

Gary Shapiro covers the opening of DIA in 1995.

9NEWS Morning Show Anchor Gary Shapiro has had a long and distinguished journalism career. He's the recipient of Murrow Awards, and he's even flown to Poland. 

But, an email about DIA coverage really piqued our attention: Apparently, Gary might have had the first of many beers sold at Denver's new airport. 

So, we asked him about that, as well as what it was like to cover the opening of DIA 25 years ago. Read that interview here: bit.ly/37PHpNU

We still miss Adele Arakawa, so it was absolutely delightful to watch her 1995 explainer videos about what to do at DIA. You might be angry about how cheap parking used to be, but you might also be happy to see how little the airport has changed.

The last passenger at Stapleton 

As you might guess, it was a ski bum. A ski bum who woke up to find himself inside of a totally empty airport.
