Narrative:

Cleared for takeoff from T 10 on runway 32L at O'hare, chicago. Had to abort takeoff roll at 75 KTS. First officer told tower of abort right away. Tower told us to taxi to the end. Seconds later tower clears a B767 going to brussels (heavy) for takeoff on same runway. We were still on runway downfield. Unsafe! Ord controllers are good, but capacity problems is pushing them to unsafe situations. Callback conversation with reporter revealed the following information: callback revealed that the controller did not give an opportunity for readback of the clearance to exit at the end of the runway. No break in the transmission was made before issuing a takeoff clearance to the heavy air carrier that was next for takeoff. Hearing the issuance of the takeoff clearance, the reporter used maximum braking and a higher than normal turn off taxi speed in order to make a runway exit at a taxiway prior to the end of the runway. There was no comment from the aircraft that had been cleared for takeoff. The reporter questions that crew's level of situational awareness. When questioned, the controller said that there was adequate spacing. He did not appear, to the reporter, to be concerned. The reporter alleges that there seems to be a deteriorating level of professional attitude and compliance with standard phraseology and procedures in the effort to move the maximum amount of traffic.
