I couldn't find a thread and it's kind of old news already in this base/speedflying world but I thought it was worth a share. Such an unbelievable feat, and to do it twice in a day, my god.
I had the pleasure of speed flying with JT and Marshal Miller; chasing them down a 3500 foot peak this summer in the Canadian Rockies. This was after standing at the exit point with some of the gopro bomb squad as they leapt off the same mountain in their wing suits. It was probably the coolest and most random experience of my life. I mean getting a phone call from JT, discussing the beta, and making a plan for early the next morning was an experience in itself. It all went down without a hitch and everyone was stoked on the morning! Such a rad crew of people.
Here's a clip from that day:
