"This license means we only have to
seek approval for significant changes that materially affect the
safety of the uninvolved public... Our goal is for RLV
developers to conduct test flights with the flexibility and ease of
development normally associated with experimental aircraft. The
terms of this license represent significant progress towards this
goal. It is helpful that RLV companies can obtain their launch
licenses during vehicle design, prior to committing capital to
build a vehicle."
