United flight turns back after passenger’s laptop falls into cargo hold

This one’s wild a United 767 from Dulles to Rome had to turn back less than an hour in because a passenger dropped their laptop and it somehow slipped through the cabin wall into the cargo bay. Since it had a lithium battery, the crew didn’t want to risk flying over the ocean with it down there. They landed safely back at IAD, found the laptop, and left again five hours later. Gotta say, turning around was the right call but how does a laptop even fit through the floor?
