If you were ever the kid that was super into planes and rockets, this is the one Smithsonian museum you can’t miss. Not even the Natural History Museum’s dinosaurs can hold up to the artifacts on display here. The only thing cooler might be dinosaurs *on* rockets, but until that happens, the Air and Space Museum will reign supreme. It’s absolutely mind-blowing that they have real-life capsules that were actually in space; You can even see carbon scoring on them. Reading the plaques alongside the displays is normally not exciting, but at the Air and Space Museum, it’s extra fascinating.
