Propane link blamed in massive blast.
An Oklahoma man was taken by helicopter to a Tulsa hospital after suffering injuries from a gas explosion at his home near Tahlequah early Sunday, authorities said.
Police say the 50-year-old man is in critical condition with third-degree burns over 25 percent of his body.
Cherokee County Undersheriff Jason Chennault said the explosion occurred around 7 p.m. near TNT Grocery in Briggs, and could be felt by residents in the area. Debris littered the highway by the house.

A new stove and heater were recently installed. Both were were propane powered.
