Into Thin Air

"Joe," I said, concerned, "hit the brake!"
 "I am," Joe said, pumping the pedal now. But the car didn't slow at all. The traffic light turned red as we hurtled toward the intersection. And suddenly I saw the one other car out this early on a Saturday morning - a huge Express Delivery truck!
 Joe screamed. I leaned forward, bracing myself against the dashboard. There was nothing we could do. It was speeding right at us!
