Congrats Jerald... so easy to miss a spot, even after thinking it all
through in advance (even after many tanks in the books ;o) ).

[quote]Yea!!!!!!!!!!!!!! The balloon is staying up. My problem was strictly due
to an oversight on my part, and not sealing the edges of the doublers
(backer plates) that extend into the fuel tank on the main spar. Although
I
had pro sealed them with Type A2 when I assembled them, I somehow didn't
catch the bottom edge where the two flanges overlapped, the spar and the
doubler. I had sealed the skin/flange overlap, as well as the vertical
seam, but for some reason didn't seal the lower seam. The air was getting
between the two on the edge and moving horizontally out of the tank. I
had
to cut a hole in the third bay, a 2
through in advance (even after many tanks in the books ;o) ).
