Hypersonic Technology Vehicle programs
The Hypersonic Technology Vehicle programs are DARPA-led experimental efforts to develop and test unmanned, ultra–high-speed glide vehicles capable of long-range flight within the atmosphere at hypersonic velocities.
-
D.
Stratolaunch carrier aircraft
The Stratolaunch carrier aircraft is a massive twin-fuselage, six-engine aircraft designed to air-launch rockets into space, notable for having the largest wingspan of any airplane ever built.
-
E.
HL-20 Personnel Launch System
The HL-20 Personnel Launch System was a NASA-designed lifting-body spaceplane concept from the late 20th century intended to provide a reusable, crewed vehicle for low Earth orbit missions and runway landings.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
