Did you possibly mean airbrushing?
“For SSTO to become real and to make sense, we need high energy-density propellants to minimize the structural mass fraction and do it without all kinds of airbreathing claptrap that has to operate in a truly rotten environment and yet be "easily" maintained.”
“The space access part comes in only if you greatly extrapolate the technology of hypersonic airbreathing engines to something much bigger and more powerful and even then only as part of a combined cycle or two-stage system.”
“Instead they became airbreathing land creatures, and food for others.”
“Diverge, and traces of a missing link lost in the sea that enlarged her form and stripped her fur and changed her contours -- and left cousins behind to revert to an earlier, more streamlined shape, but still airbreathing and milk-nursing.”
“Insects and scorpions have been found in the "Silurian." [tr. note: sic on punctuation] They stand among the highest of even _living_ articulates, and they are the "oldest" known airbreathing animals.”
“Pentagon crazytech agency DARPA also has aspirations to use technologies from the HTV programme in airbreathing scramjet missiles or even re-usable manned aircraft.”
“And, of course, horizontal takeoff with some degree or other of airbreathing, to reduce on-board oxidizer weight. (at the price of a more complex engine, possibly heavier than a pure rocket of the same thrust, especially for scramjets where a large part of the structure must be devoted to variable inlet issues)”
“On the path toward her goal she will fulfill a NASA internship this summer in Langley, Va., working in the hypersonic airbreathing propulsions branch.”
“The only marine organisms left alive are some airbreathing limpets and a few black mussels. ”
“The most promising way to meet this challenge is to extend aeronautical technology to hypersonic vehicles powered, at least partially, by supersonic combustion airbreathing engines”
