They were traveling in the same type of glider they had used on the leg from the Cayambe socket to Magdalena. Because it had no engines, it could fly through the Ashwall without mechanical damage, and because it traveled more slowly than a jet, they didn’t have to worry quite so much about Kath Two’s windshield getting fogged by abrasion from microscopic bits of rock. They did have to be somewhat concerned about the fact that she could not see where she was going as they flew through the densest part of the cloud. But she knew the altitudes of the nearby peaks and stayed well above them. Once the view had cleared a little bit, she was able to take advantage of the ash, which worked in the air somewhat like a drop of ink in swirling water, making currents and vortices obvious.
