.. unusual for me but I watched that episode ... the problem is not a little hole (remember that the outflow valve is letting air out as well .. not to mention all the other leaks in the hull) .. but either a big one (window/hatch lets go) or a tear (a la the Aloha convertible) ..
An entertaining program at times but a bit long on waffle and TV razzmatazz and usually pretty short on the technical stuff ...
