The sharp summer heat may have slightly stifled attendance of the 2017 International Paris Air Show on the first day of all its splendor, but the world's largest aerospace exhibition was back to its usual vigor by the second day with its engines blazing.

Thousands of spectators visit the air show every year to inspect and explore the latest technologies and breakthroughs in aeronautics and space science. Representatives from commercial airlines, private companies and military forces from various countries also keenly observe the event's marvels.

A key occurrence at the international exhibition was the American aerospace giant Boeing's (BA  ) emergence as the champion over its European adversary Airbus (EPA: AIR). Boeing concluded the show on a very positive note as it snared 571 orders and commitments valued at $74.8 billion at list price. Airbus, on the other hand, received orders for 346 airplanes worth $42.2 billion even though Patrouille de France Alphajets escorting a double-decker Airbus A380 opened the show.

Sales of both Boeing and Airbus were mainly met by impeccable demand of Asian and Iranian airlines. The single-aisle jets dominated the annual showcase in Le Bourget.

However, Airbus seems to be more efficient than Boeing when it comes to doling out products fast enough to meet demand. Considering that Airbus has 30 more orders than it did in 2016, it is looking to make its production process faster and more efficient in the latter part of the year in order to be able to cater to increased demand.

The narrow-body jets dominated the show with the long range twin aisle accounting for less than 10% of the total sales as airlines are looking for cheaper and economical aircraft. The combined new business deals struck by both the airplane manufacturers amounted to more than $114 billion at the Paris Air Show, though customers would be paying much less, thanks to the profound discounts.

Other points of interest was two F-35A Lightning IIs arrival at the Paris Air Show to fly the aircraft's first public aerial demonstrations, which allowed the U.S. to make history. Pulling off a remarkable event such as this takes months of careful planning and preparation. Yet, this team had only 36 days to make it happen.

"You have two Air Combat Command (F-35A) jets being maintained by 39 ACC Airmen, flown here from the U.S. by two Air Education and Training Command pilots and we are using a Lockheed Martin demonstration pilot to perform in the show," said Col. Justin Hickman, head of American Air Forces in Europe.

Spectators were also given thrilling Virtual Reality experiences through which they could truly experience the adventure of flying such dynamic aircrafts. To further enamor the audience, attractions like the Airbus Tiger HAD Attack Helicopter and NASA-developed Mars 2020 Rover were on display.

What's more interesting is all the prospects there were for future technologies upon Earth itself: AeroMobil, which has received almost $7 million in Slovakian government subsidies, is competing with visionaries like Google's billionaire co-founder Larry Page to roll out a flying car. Spectators could even interact with such a vehicle, being able to access a touch-screen map and steering wheel inside its cockpit.

The week-long event wrapped up the evening of June 25. As the announcers informed everyone to make their way to the exits, crowds still gathered around the U.S. corral to get one last look at the airpower on display at the Paris Air Show.
