I was browsing through the pictures and found this one which indicates a Delta MD-88 with damage during pushback in Denver in April of 2003. Anyone have any info on this? As a former Ramp Agent for Delta in DEN I of course am interested.

The COA EWR thing came up recently, but in a nutshell, overnight MX was done on something on/near the throttle quadrant and the thrust levers were moved out of their normal idle thrust position. When this work was done, they were never returned the thrust levers to their normal idle thrust position. A second mechanic was working on an engine later, and when done, had to accomplish an engine run for leak checks or whatever. He started the engine, not noticing the out-of-position thrust levers, and when fuel came in and the engine lit off, the aircraft jumped the chocks and went into the building. One other fellow who was at EWR chimed in that he'd heard that the mechanic was kneeling over the throttle quadrant to run the engine, and wasn't in the seat itself, and thus unable to even apply the brakes.
Heck of a waste of a good aircraft, which was written off...

I can tell you that the push back tugs delta had in DEN as of the late 90s were 3 VERY heavy Tugs, 2 were old and 1 wasn't all that old, but none the less that had to have been some serious power to move that Tug like that. And a MD-88 at that! I know the JT8Ds are good engines but my gosh! I would think that the towbar would have bent in half before getting the tug to jackknife. I am very glad that no one was injured in particular the ramp crew, I can just picture myself disconnecting the towbar from the front wheels and then having the aircraft move forward like that. Would have scared the heck out of me!

Something similar happened when I worked for DL in BWI a couple of years back. It was wintertime and the ramp had several patches of ice and packed snow due to a recent snowstorm. We had a 727 with an inop APU which needed an airstart. The Captain requested to start all three engines at the gate instead of starting one or two and then using the crossbleeds to start the remaining engines. We advised against it because of the icy ramp and the fact that three operating JT8's have a considerable amount of thrust even at idle. Also, the pushback we had at the time was pretty old and had trouble pushing back aircraft even during good weather conditions.
During pushback, with the tug and towbar at about a 45 degree angle to the aircraft, the airplane started rolling forward. The pushback driver tried to straighten the towbar but the tug did not have enough traction on the icy ramp and the plane was actually pushing the tug sideways. The headset cord snapped and and one of the ground agents tried to give the "set brakes" signal to the crew, but apparently they were busy with a checklist and not paying attention. As the airplane rolled forward it bent the towbar about 90 degrees and finally came to a stop when the plane hit the corner of the pushback cab puncturing the fuselage.
Fortunately no one was hurt but the flight was cancelled and the aircraft was grounded for about a day while a temporary repair was made to get it back to Atlanta. I don't know the details of the investigation but I believe the crew was found to be at least partly at fault for not paying attention to hand signals from the ground crew.
