"I have heard that reactors are designed to withstand a 747 impacting at full speed."

I have read the same. Regardless, it would shut down power generation for months/years. Impact on economy?

Despite the veracity of this statement, makes you wonder where the other planes were headed (I would guess more than 4 hijackings were planned). More infrastructure destruction, no doubt. Why not power grids?

Impact maybe. What about the ensuring fire?

Half that plant is already (obviously) shutdown so the "power generation" effect is neglible ..... the containment walls and small size of the target, plus the fact that the core and internals are "submerged" in ten-foor plus concrete shield walls) make the real danger much less than you'd imagine. <P.... little impact EXCEPT the "TMI"/"nuclear power plant" name recognition that this thread represents in full measure!
