• 4. Just What is the Right Color for These

Birds?

c JOG System Engineering 103A-11

High Altitude AQM-34R/147TF Used for Signal Intelligence in Flat Black Paint Job

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

• Crate of North Vietnam 5 Dong

bills in the hangar

• Picture and psywar message
• Alternative use of the money

• 7. Flying a Bit Too Low

c JOG System Engineering 103A-15

THE FAA FROWNS ON THIS SHIT!

• 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
• f 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."

• 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

• 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

• 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
