I heard the same thing!  The Jews planned it all to turn the world against their enemies in the middle east.  Suicide troops disguised as typical hymie money changers had infiltrated the towers and set explosive charges on each floor so that when the planes hit they could set them off.  To add to the dramaï»¿ they siezed some of the Gentiles and sent them hurtling to their deaths.  The planes were flown by more Jewish forces that had surgically altered appearances and forged passports.
