Rear air bag failure

Returning home to Ga Monday, just crossed into Ga on I75. Heard loud explosion. I was sure it was a blowout. Got stopped , checked things out and seen the air bags on rear were Down. Limped to next exit about a mile, Luckly a truck stop with a repair shop. I crawled under and could hear air but couldn't find it. Shop took it right in and found it. Hole in left rear bag at the top. About 1 hr to remove. No air bag to be found so will be here Tuesday. I am going to replace the right side when I get home. I don't recall reading anything on airbag failures on this site, so I would like to here from you folks. Guys at shop say it is fairly common on tractors. Also another reason to try and avoid Sat. or Sun. travel if possible. Thanks
