Hi Mike and all tektitophiles, have a look on my website <http://webplaza.pt.lu/guyhein/index.html>. My book ' Tektites - witnesses of cosmic catastrophes' gives an explanation on impactors hitting Earth under a very oblique angle and producing tektites. The book collects a lot of research from renowned tektite researchers and supplies a plausible theory.
