Hand catching a flying multirotor/drone.

Now I have done this in an emergency situation - retractable landing gear failure, to save craft & camera damage.
I wouldn't recommend doing it for no good reason though as some of the larger multirotors will takes your fingers right off if you fumble it.

Just ask Enrique Iglesias how dangerous it is.

NEW YORK — Enrique Iglesias was recovering Sunday after some of his fingers were sliced when he grabbed a drone during a concert in Tijuana, Mexico.
A representative for the singer said in a statement to The Associated Press that Iglesias was "semi-treated" after the accident at the side of the stage to stop the bleeding on Saturday night. He was advised to end the show but went on to perform for an additional 30 minutes.
"During the show a drone is used to get crowd shots and some nights Enrique grabs the drone to give the audience a Point of View shot. Something went wrong and he had an accident," the statement read. "He decided to go on and continued playing for 30 minutes while the bleeding continued throughout the show."
Concertgoers at Plaza de Toros de Playas posted photos on social media of Iglesias, 40, with blood all over his white T-shirt.
"He was rushed to the airport where an ambulance met him there. He was then put on a plane to L.A. to see a specialist," the statement read.
