DHL is the largest air cargo operator out there. Although they don’t really have an airline, so to speak, they contract with other carriers who paint their aircraft yellow and operate on behalf of DHL. About 15 years ago, they had largely pulled out of North America. That trend has reversed and on any given night, Cincinnati airport sees more than a dozen 747s, at least as many 777s, a bunch of 767s along with 757s and 737s……..hey are back in the US to stay.
With respect to the 757 crash, he pilots notified departure control that the had a left hydraulic system issue and would need to return. Because the 757 is not equipped to jettison fuel, they lingered offshore to burn off some weight. Even at that, it would have been a heavyweight landing. It appears hat the brakes were locked at, or shortly after touchdown and I suspect the right main tires blew which is what caused the airplane to veer to the right. When they hit the ditch, he tail and one wing snapped off.
