4. Just What is the Right Color for These Birds? High Altitude AQM-34R/147TF Used for Signal Intelligence in Flat Black Paint Job c JOG System Engineering 103A-11
A Chase Pilot's Story • Navy studies indicated strike aircraft survived well with colored paint jobs even using bright colors • First few production 147SK birds had camouflage paint jobs but later deliveries used glossy black • Chase pilots assigned to unmanned recce flights because of a problem later traced to poor E2B remote control antenna pattern • Chase pilot had chased a black drone earlier and had no problem following it through its mission • Same pilot chased a camouflage grey vehicle and complained he could not see it in the grey skies over Vinh unless he was very close c JOG System Engineering 103A-12
5. When SAC and Heaven Were Neighbors VERTICAL STABILIZER FIN CAP AND MCGS ANTENNA FAIRING DAMAGE FROM HAIL "In the future there shall be no hail storms in the path of the vehicle" c JOG System Engineering 103A-13
6. Money to Burn • Crate of North Vietnam 5 Dong bills in the hangar • Picture and psywar message • Alternative use of the money c JOG System Engineering 103A-14
7. Flying a Bit Too Low THE FAA FROWNS ON THIS SHIT! c JOG System Engineering 103A-15
8. Falling Out of the Air • Stall before completing post launch acceleration • Is it an aero or mass properties problem? • We all understood mass • The next tech rep scheduled for deployment gets the job • Ballast briefing c JOG System Engineering 103A-16
9. Safety First at All Times • Target service for the whole world • Automatic launcher braking debunked • Bomb assembly on the mess deck and loading on the flight deck • BGM-34C booster armed alert c JOG System Engineering 103A-17
10. Destructive Design Change • Ground launchers had to have an engine inlet scoop to avoid engine stagnation during run up to launch rpm • One designed into Model 147SK launcher • Model 147SK vehicle used ASROC booster because of greater weight than BQM-34A • On first launch, ASROC booster blast tore the inlet scoop completely off from the launcher • Decision to eliminate scoop schedule driven c JOG System Engineering 103A-18
11. A Hard Sale • Top marketeer goes to Israel to make unmanned aircraft sale • Golf courses • Pyramids • Please leave • Two field engineers to the rescue – one of whom had been told to leave OL-20 before the sun went down in the beginning of this story c JOG System Engineering 103A-19
12. Misunderstood Humor • Model 147SK first launch – Engine exhaust impingement on ASROC booster misjudged – Mark on booster telling direction of exhaust misalignment not clearly understood – Interesting launch trajectory – Admiral's new red Cadillac • Model 124I first launch – Launcher position at Bir Gif Gaffa – Launch trajectory disappointing but hilarious to some - "We may have overcompensated a little." c JOG System Engineering 103A-20
13. Scared to Death • Mother of tech rep deployed to Bien Hoa for super secret black box dies • Good son returns to states • No flights except Air France • Air France alternate landing rights in Hanoi • Engine trouble c JOG System Engineering 103A-21
14. For the Love of a Program Manager • Pilot reminiscing about prior unlucky launches with Ryan field engineer • First launch of new Model 147J low altitude photo reconnisance aircraft from DC-130 in flight test • Program Manager goes on flight with Ryan field engineer • Field engineer draws his parachute • At launch the bird took off the DC-130 number 3 engine • Program Manager, who did not draw a chute, had the field engineer's chute on very quickly c JOG System Engineering 103A-22
15. How to Talk to a Dancing Bear Rat in the rain barrel • Hum three bars and I’ll take it from there • Let’s make it out of balonium • We’ve bent our pick • Load down the wagon • Snapping your fingers to keep the elephants away • Big fat umbilical • Little bit of blood • Lets make sure that we get the goose grease on it before you pluck • the tail feathers Bit in the rump • Couldn’t get ten bucks for a Rolls Royce with this name on it • Another ladle in the well • c JOG System Engineering 103A-23
