Brief Description: Checking the balloon (leak test)
It has been 27 hours since the left fuel tank was pressurized and so far it shows no indication of leakage. I plan to watch the balloon for another day or two but maybe, just maybe, I actually built a leak-free tank. Being a "glass is half empty" kind of guy, however, I won't claim success until the tank is full of avgas on the tarmac on a hot summer day with no blue stains!
