North Carolina Republican Rep. Renee Ellmers celebrated the event, which took place in her state, in a tweet. So did GOP Whip Kevin McCarthy (R-Calif.), who is known for tweeting about anniversaries large and small.

"Wilbur and Orville Wright were the kind of entrepreneurs Americans everywhere root for," reads the presidential proclamation marking the national observation day.

"With their game-changing feat, the Wright brothers earned their place in history as innovators who helped trigger America's rise as an economic superpower, and whose example inspired the kind of businesses and industries that built and grew our middle class," it says. "As we mark Wright Brothers Day, let us carry their legacy forward by taking on new challenges with tenacity and meeting our hardships with courage, confident that our shared future is bright and our best days are still ahead."

Dec. 17 has been Wright Brothers Day since 1963.
