High speed video (300fps/one tenth speed) o' t' very first fire on Masten Space Systems' new VTVL rocket vehicle, XA-0.1B. A four engine vehicle, ya bilge rat, this is engine Y+. Aye aye! This first test is a start abort, where immediately after startin' t' engine, t' throttle valves are closed and t' engine is shut down. T' cool fireball is isopropyl alcohol bein' ejected from t' engine and burnin' in air; it is expected in a start abort and causes no damage. Well, blow me down! T' blast deflector was damaged durin' testin' o' XA-0.1, and further damaged by me backin' a pickup truck into it. T' concrete pavers are tossed off when an edge is in t' flow, and you can see one break by hittin' another before it even reaches t' ground. Avast! We tweaked t' frame, ya bilge rat, put pavers back on, and it worked fine for t' subsequent tests. More information at www.masten-space.com
