B-25: 33,000lbs @ 225 mph

vs

767-200: 300,000 lbs @ 500 mph

so, roughly 10x the weight at 2x the speed

If those numbers are correct, that's 40x the energy.

40x the kinetic energy. Now consider the chemical energy stored in sufficient fuel for a coast to coast flight of that weight and speed.

rough approximation, but I did double check the numbers.

ie we don't know the exact weight of the bomber, but that's its average laden weight, could be lighter without bombs

in 2001 the second plane hit faster than the first and I believe the first is guessed from footage but the second is from the black box?
