I think what's sad is not that they shut down the project soon after acquiring Titan Aerospace, but that they kept it quiet for almost a year. That sort of PR practice makes me worry about their internal culture.

Edit: It concerns me because I wonder how many other projects they've announced and shut down without telling us, and what that must be like for the employees who are no doubt under NDA who are shuffled around and unable to talk about it. Imagine if your company were acquired by X, and then you get fired, and you can't even tell your friends or potential employers it's because X axed the project.
