RENO, Nev. — The head of the Reno Air Races Association said Thursday he expects to secure the required $100 million in insurance and all the permits needed to run the 50th annual national championships in September, despite a deadly plane crash at the event last year.

But a longtime critic of air race safety told an airport authority panel that officials are moving too fast in the wake of the wreck that killed 11 people and injured more than 70. The Reno races are the only ones of their type held anywhere in the world. A group of planes flies wingtip-to-wingtip as low as 50 feet off the sagebrush at speeds sometimes surpassing 500 mph.
