umccall+Follow11 Undersea Tunnels That’ll Blow Your MindEver driven under the ocean? These 11 undersea tunnels are wild feats of engineering—think Victorian Londoners battling floods, Japan’s bullet trains zipping beneath the sea, and Norway’s roads plunging deeper than skyscrapers are tall. There’s even a tunnel with its own island rest stop! Each one proves humans just don’t take ‘impossible’ for an answer. Which one would you dare to visit first? #TravelGoals #EngineeringMarvels #BucketList #Transportation101Share
Nicole Morgan+FollowThese Military Machines Are Absolute UnitsEver wondered what happens when engineers decide to build military vehicles with zero chill? Meet the heaviest beasts ever to roll, fly, or sail—like the T-28 tank (38 pickup trucks heavy), the Spruce Goose (a flying boat the size of your street), and the Typhoon-class sub (an underwater city). Some were so massive, they needed their own railways or could carry space shuttles. Forget stealth—these giants were all about flexing pure, unfiltered power. Which one would you want to see in person? #Cars #MilitaryHistory #EngineeringMarvels150Share
