Curiosity, a set of NASA 's robotic "eyes" on the Red Planet, recorded 16 minutes of so-called noctilucent clouds flying ...
Some people enjoy watching clouds, but I prefer contrails ... I recently took a photo of a trail following a plane flying above the Sutro Tower, rising from the city’s heart.
Confused? Well, so were the residents of most high-rise buildings in Uttar Pradesh’s Noida and Greater Noida, after they woke up to an ‘above the clouds’ view, without even flying!
