While focusing a telescope on objects in deep space, researchers happened to collect images that enabled them to answer a question much closer to home: How wide are the glowing
vapor trails known as meteors?
Therefore, an important factor in air combat becomes finding a layer of the atmosphere where one's plane does not produce a vapor trail, yet one that is high enough not to seriously compromise the advantage of superior altitude.
Where this mechanism was concerned, the subcommittee cautioned that the presence in engine exhaust of sufficient water to produce a condensation trail did not necessarily verify this mechanism as a cause of vapor trails. (16)
Of central interest in this February 7 report were vapor trails spawned by engine exhaust and the atmospheric conditions that would permit their formation.
Air crews also felt that vapor trails increased the danger to bombers at their most vulnerable moment: the bomb run when planes flew straight and level to ensure bombing accuracy.
From that, Lehmacher and his team can analyze upper-atmospheric winds by tracking how the
vapor trails form, billow, disperse and diffuse.
Although pilots were accustomed to seeing
vapor trails in the 1920s and 1930s, they were not well understood.
In the poem "Dry Heiligenschien," she writes: "the dream field with
vapor trails pinned / against the sky." And later in the same poem, she gives us: "cantered bareback / through blistered furrows." Again, using nature within her images in "Forbidden Fire," she describes girls that are "thin as April sap." Terris's inventions make readers stop, reread, and enjoy again.
In April this year the band released Snakes and Arrows, their first all-new album since 2002's
Vapor Trails. "Our current liveshow is about three hours long and we'll be concentrating on the new album, doing about nine tracks off it," says Alex.
RUSH have ended a five-year absence from the recording studios with new album
