In the midst of this atmosphere of optimism and change, Timothy McVeigh drove a rented truck full of explosives to the Alfred P. Murrah Federal Building in downtown Oklahoma City on April 19, 1995. The explosion killed 168 people (including 19 children) and injured more than 680, as well as damaging and destroying many surrounding buildings. Until the attacks of September 11, it was the largest terrorist attack on American soil, and it remains the single largest domestic terrorist attack in American history.
