I just looked this up on the Madrid bombings

07:39 - Three bombs explode on train 17305 by Téllez street, 500 meters (547 yards) short of entering Atocha station. Seconds later, four bombs explode on train 21431 on track 2 inside Atocha station.

07:41 - Two bombs explode on train 21435 at El Pozo del Tío Raimundo station.

07:42 - A bomb explodes on train 21713 at Santa Eugenia station




9/11 attacks:

8:45 a.m. (all times are EDT): A hijacked passenger jet, American Airlines Flight 11 out of Boston, Massachusetts, crashes into the north tower of the World Trade Center, tearing a gaping hole in the building and setting it afire.

I am guessing they chose the times to cause the most casualties.
