It really is raining on their incredible aerial parade - but the crowds below loved it. Incredible photos have captured the US Air Force's F-22 Raptor Demonstration Team kicking up clouds of moisture as they race across the Chicago skyline. The small clouds formed on the wings of the fighter jets when they performed high G-force maneuvers, which caused the air pressure on the upper side to drop. This made the temperature fall quickly and water vapor in the air condensed into clouds. The 60th annual event saw the planes fly across Chicago's famous waterfront and duck and weave between the towering skyscrapers to the cheers of more than two million onlookers last weekend. 👩‍🚀 much #WOW

Tens of thousands of people held hands across Hong Kong late Friday in a dazzling, neon-framed recreation of a pro-democracy 'Baltic Way' protest against Soviet rule three decades ago. The city's skyscraper-studded harbour-front as well as several busy shopping districts were lined with peaceful protesters, many wearing surgical masks to hide their identity and holding Hong Kong flags or mobile phones with lights shining. The human chain is the latest creative demonstration in nearly three months of rolling protests which have tipped Hong Kong into an unprecedented political crisis. #HK much #WOW

Brazil's President has indicated he could send the military in to fight the massive blaze engulfing the Amazon rainforest as the international outcry over the disaster continues. Jair Bolsonaro did not say when the armed forces would get involved, but said 'that's the plan' and suggested that action could be imminent. Mr Bolsonaro has previously described rainforest protections as an obstacle to economic development, sparring with critics who note that the Amazon produces vast amounts of oxygen and is considered crucial in efforts to contain global warming.
