The 'Furious 7' plane that just won't quit

Marietta, Georgia (CNN)The little-known star of this week's No. 1 car chase movie, "Furious 7" isn't a car. It's an airplane.

Film producers hired a Lockheed C-130 Hercules to fly five cars 12,000 feet high, open a cargo door at the rear of the plane and parachute them out in a spectacular free-fall stunt.

Geronimo!

Happy 60th birthday to the Hercules -- the oldest continuously produced family of military planes in history.

Lockheed has been making these airplanes longer than the legendary B-52 bomber and the famous U2 spy jet. Unlike those planes, the C-130 has never become a household name.

The fact that "Furious 7" producers chose a plane that was designed in the 1950s tells you a little something about the success of the Hercules.

The film makes it appear as if another plane -- a C-17 Globemaster III -- drops the cars. But in real life, it took a Hercules to pull it off.

Shooting the scene posed unique logistical challenges, said stunt coordinator Jack Gill in a featurette video about the mission. "You start throwing all those cars out together -- you've got to figure out spacing. And these things drop very fast," Gill said.

Jeremiah Beaudin of International Air Response co-piloted the stunt. "We have to be very precise in our headings and our altitudes," he says in the video.

 The Hercules is big. It's tough. It's versatile. It refuels helicopters in flight. It can fly a small military force and its heavy equipment around the world -- and land on short, unfinished airstrips.

At Lockheed's Marietta, Georgia, factory in 1955, the governor of Georgia christened the first production C-130A by smashing a bottle of Chattahoochee River water across its nose. The plane then proceeded to take off from nearby Dobbins Air Force Base.

 On Tuesday, exactly 60 years later, Georgia Gov. Nathan Deal recreated the ceremony -- christening a brand new Super Hercules during a birthday party of sorts for Lockheed executives and military dignitaries.

"I'm told that the 2,500th version of this aircraft is now on the (assembly) line inside this building," Deal said. "It transports, it becomes a war airplane as necessary and it is recognized as the true workhorse."

Inside the plane's cockpit, Lockheed test pilot Steve Knoblock said he's done a lot of air-drop testing while flying C-130s. "We've dropped some crazy things out," Knoblock said. "Air dropping a car out of an airplane is easy. Whatever we can fit inside the (cargo) hold, we can drop."

Several factors come into play for a pilot making a drop, Knoblock said, including payload weight, wind speed and timing.

"We have to give time for the car to clear the airplane, let the parachutes deploy, and then actually open," he said. One tricky decision involves how high the plane drops its cargo.

"There's a trade off -- between dropping it low and being more accurate ... and dropping it high where you have a little more safety in how it will land."

Knoblock also explained how the C-130's robust landing gear helps the plane survive difficult landing conditions.

"The pilot gets to decide how hard the touchdown's going to be," he said. "Sometimes to get his performance, he needs to really let it crunch on the ground. But the airplane can handle it."

Meanwhile, in the back of the plane, Lockheed loadmaster Lucky Madsen showed off the plane's new reversible deck, which makes it easier to switch the floor from a flat surface ... to a floor with rollers embedded in it. The rollers make it easier to move cargo around and launch it out the back of the airplane.

The legacy surrounding the Hercules has been built by 60 years of successful missions, including:
