- big_toast 6mo agoI found a link that said they were discussing the testing schedule with media, but haven't found a timeline for when they might go supersonic. First X-59 post on hn was 8 years ago!
- big_toast 6mo ago"The X-59’s thin, tapered nose accounts for almost a third of its length, and will break up the shock waves that would ordinarily result in a supersonic aircraft causing a sonic boom."
