# Observers at rest and simultaneity

Suppose we have two observers A and B and they are at rest. Observer A observes two objects falling from height H (A has same distance between the two objects). Does observer B will measure different times for the duration of falling of the two objects ? (because the two object are not in the same location therefore a finite time interval must exist for the information of their position to reach B).

But the time that A measures between the events "the object starts to fall" and "the object lands" is the same as the time that B measures between the events "B sees the object start to fall" --- because $$A$$ and $$B$$ are smart enough to correct for the finite speed of light.
