I roughly get relativity in broad terms. I get that if you are in a car and throw a ball backwards at the same speed as the car is travelling forward then to you the ball flies away from you but to someone stood by the road the ball drops straight down but this falling lab one seems wrong in my mind unless the light falls faster than the lab is falling.

Now, Alice has cloned herself. She's sitting at one end of a table in the BoxLab facing her clone at the other end.
There's a lamp on the table between them. The Boxlab instead of falling vertically is moving at a constant speed horizontally.
Alice flicks a switch and the lamp comes on. The light from the lamp hits Alice's face and her clone's face at exactly the same time.
Is this what Bob sees?
