NASA Solicitation: Parabolic Flight Services (Zero Gravity Corporation)
"Zero Gravity Corporation is a unique organization that has a FAA certified aircraft to supply 2 reduced Gravity Flights for approximately 2.0 - 3.0 hours per flight. There is no other organization in the Parabolic Flight Services industry that can provide such a unique requirement of reduced Gravity Parabolic Flights."
Editor's note: It is good that NASA is (finally) going to the private sector for such services. However, have a look at the services offered by Atlas Aerospace. Perhaps the procurement notice should have read "no other domestic organization..."
