Hey, that's just the way JFK is. I thought it happened closer to 1900 local. I looked up from my beer and saw a bunch of trucks in procession behind an Egyptair triple taxiing in on Hotel. The VS being towed behind it also had an escort. I couldn't spot the damage in the dark, but I had already notched it up to yet another Kennedy taxiway wing-clipper.
So you don't even need to be an armchair pilot to blame JFK. All you need is a window and a cool pint. Wingtip clips at JFK are like RAs in Spain: they seem to happen more often there than elsewhere, and, while in each case the aetiology might differ, a large factor is systemic, such as a bunch of heavies crammed into a space designed for the occasional 707.
