i just watched on cnn an eyewitness to the event.
she said the brakes overheated and caught the wheels on fire. they ran up to the bus saying "get out" and no one was moving. when she entered the bus, she realized that they were elderly and many needing wheelchairs to get around. many on oxygen as well. it was that oxygen that caused the bus to explode. 24 people were lost. truly a sad day.
