I see the planes at the rear touch down first. If the front planes landed first they would slow down and the rear planes would run into them.
they had to have a real long runway to do that that first plane (last one) that touched was over 1,000 ft from the approach end and at the speed they land the front planes surly had to do some serious breaking, the turbulence must have really been something, whew
simply Amazing and what skill...
