upsun

[Jonathan Lighter]

Not in OED in this sense, "_Aerospace_. in or into the direction of the sun; sunward":

  1943 Arthur G. Donahue _Last Flight from Singapore_ (N.Y.: Macmillan) 63: Where we could be "upsun" of our enemies. Ibid. 76: I got above and upsun.

  1975 J.R. Daniels _Firegold_ (N.Y.: Coward, McCann & Geoghegan) 93: At nine thousand feet, well south of the massif, I could look upsun along the coastal plain towards Malili.

  1989 Tom Blackburn _The Jolly Rogers_ (rpt. Osceola, Wis.: MotorBooks, 2006) 124: We could not figure out why six up-sun Zeros with the altitude advantage had failed to attack the Corsairs.

  1996 Barrett Tillman  _Hellcat Aces of World War II_ (London: Osprey Aerospace) 13: Placed by the radar controller in 'a fighter pilot's dream position' 4000 ft above and 'upsun' of the 24 enemy aircraft.

  2003 Norman "Bud" Fortier _An Ace of the Eighth_ (N.Y.: Random House) 130: They...were suddenly greeted with plenty of flak. Curt decided to fly upsun for several miles, then dive down to the deck...and maybe surprise the flak gunners.
