TWIN FALLS, Mont. -

Two daredevils hoping to succeed where Evel Knievel failed 40 years ago in jumping the Snake River Canyon in southern Idaho are looking at delays due to television scheduling.
    
The dates for the jumps are being pushed back to late September or October.
    
Texas motorcycle daredevil "Big Ed" Beckley says he'll clear the chasm on a rocket-powered motorcycle.
    
Hollywood stuntman Eddie Braun says a steam-powered rocket will carry him to safety.
    
Fox Television in May agreed to broadcast both attempts, possibly on the same day.
    
Knievel, who died in 2007, failed in to make it across in 1974 in a rocket-powered "Skycycle" when the parachute malfunctioned and deployed after takeoff.
    
Strong winds blew the cycle into the canyon, landing him near the swirling river below.
