I have a couple of sewups with casing failure but not that severe...
This one had a mini bump but I'm sure it would have blown out.
I carry some of the super tough plastic material that USPS envelopes are made of just in case I ever have to put a boot in a tire to make it home.
On a ride one time, my buddy had a casing blow on one of his high pressure "zoomy" tires. All we had between us were $20 dollar bills to use as a boot. Usually a $1 bill will work just as well...
