Perhaps the most obvious is flying tiny quadcopters (about 1 inch on each side) in your living room. But for years, hobby groups have formed relationships with schools and churches to have meetups in their gymnasiums. It's not limited to propeller-aircraft; ultralight rubberband power fixed-wing is a popular indoor option. And FPV enthusiasts can get competitive by setting up race courses in parking garages.
