The money invested by government agencies, institutions, and the public, came with an implicit expectation that there would be very large, outsized returns within a reasonable time frame. That's why an IPO is more expensive than debt, they signed up to meet high expectations. Otherwise, why would anyone be willing to stomach the opportunity cost of investing for this long?
I know the baggage scanner and CT are the big products, but this one has to deliver, they have to demonstrate that the money they spend produces value for customers and investors - otherwise it isn't a viable business. They need to be able to show they can actually sell what they make at volume, the next 12-24 months should be indicative as to whether or not that is the case.
