This looks like a dramatic scene, but it’s really just part of the denouement of a book that’s going to run to 101 pages. At least, 101 pages of comics — there will be an acronym glossary, title page &c.
I’ve never seen an explosion take a window clean off its hinges like that; it was just easiest to draw and convey what was happening. On a window that swings open on hinges, the latch is typically much weaker than the hinges and fails first in this sort of scenario, causing the whole thing to swing 180° and hit anyone who happens to be in the way as it goes by. Duct tape, of course, keeps the glass from shattering, or at least contains it.
