This classic video footage comes from the 1973 P.R.O. event in Tulsa when John Wiebe and Jeb Allen became entangled in a nasty crash during eliminations. Allen suffered substantial burns on both hands and Wiebe suffered a broken leg and ankle. A tire issue apparently led to Wiebe's car darting into Allen's lane where they made the initial contact.
