    Was it stored in a humid environment? That sounds like the BP was damp and thus didn't burn.

    So I have finally got around to properly having a look at what remains of the soyuz, and begging her rebuild!

    Cutting back the damage was fairly gutting, however at the end of t have half a core stage that I know i can repair without to much challenge.

    The lower section needs a little work there s a small crumple n the middle of it, the centering rings at the inter stage gap need replacing and the inner tube straightened and reinforced with coupler, the rest is fairly cosmetic. From here on up its a total rebuild.

    Another part of the rebuild will be the igniter system which took a rather heavy hit in the last launch.

    I have straightened out the remains of the core now, sanded back the damage, stiffened up the crumple with super glue and repaired the minor cosmetic cracks. The inner tube was then straightened with a piece of coupler and a new centering ring and extension tube glued in place ready for the upper part to be rebuilt.
