Am on phone so can't go double checking, but I believe it was definitely explained in this one: https://m.youtube.com/watch?v=MGdxpqqsHl8 https://m.youtube.com

The planes definitely leaked at low temp eg on the apron but not much at all; just a few drips. The problem was the tires were gonna burst if you aborted a takeoff with a full fuel load and had to land immediately. It was a weight problem. Murray takes about it at length and even says he has a tire at home in the garage. He also hands around other bits of the plane so people can see the honeycomb etc.
