When the USAF had heroes!
F-100 Super Sabre had a large chamber that accepted a large gas generating cartridge. When ignited by electrical current, the expanding gas from the black powder-like pyrotechnic cartridge drove a starter turbine that brought the engine up to a self-sustaining RPM. This device eliminated an absolute need for using slower, bulky ground starting units. On the other hand, the cartridge spewed out a characteristic dense cloud of choking black smoke, often mistaken by inexperienced ground crews as a true fire emergency. The powder charge for the ground start came in a big sealed can, and on opening and extracting the cartridge, you'd find two small metal tabs on the bottom of the cartridge. These tabs were the electrical contact that fired the cartridge when the pilot moved the throttle outboard on start. As soon as a tiny RPM registered on the tach, you brought the throttle around the horn to feed fuel and ignition to the rapidly-building engine speed. Sometimes, the big metal receptacle holding the cartridge would get so dirty from repeated use that the metal tabs wouldn't make contact. Then the cartridge would deny firing to fire, so the crew chief would smack the starter receptacle with a wooden wheel chock, usually curing the device of any reluctance to detonate. We'd often take a starter cartridge can along with us as an alternative starting method. The story is told, of USAF Captain John Green who had stopped in at Memphis MCAS, in an F-100 way back in the early '70s. He was approached by Marine crewmen, who then asked what kind of plane he was flying. Green's slightly lofty response called it a ' S-U-P-E-R ' Sabre. The tenor of his reply merely generated increasingly puzzled stares from the inexperienced ground crewmen. One of the ground crew said, ' Sir, I don't think we have tech data on this bird. What will you need for start . . a ' huffer' . . or just an electrical jolt from our APU ?' His eyes glistening considering a practical jokers dream . . but poker-faced and without pause . . he turned to the young Marine crewmen and told them : " NEITHER ONE . . GUYS ! " " You've got me fueled up. So just pull all the pins and hand them up to me. Then, get at least six ( 6 ) buddies from the other crews to give me a brief shove toward the active runway. After you get me rolling at a fast walk . . everyone just stand away from the tail pipe when I ' POP ' this SUPER Sabre's . . CLUTCH ! Then stand back and watch this ' thing ' start . .. just by using the muscle energy you've volunteered." More and more puzzled glances from the ' greenie ' Marines . . all of their mouths opened a bit in wonder as they thought of something to say. What else would a young Marine say ? And " YESSIR ! Let's do it . . became their ringing response. " The Hun was pretty finely balanced on the two main gear struts. When you tapped its brakes, the nose strut compressed so much that the F-100's nose took a dip, just like our cars' hoods dipped when we occasionally ' clutch started ' following a dead battery push from our buddies while ' drag racing ' our hot rods. So now . . still doubtful . . six Marines are standing at the ready . . but they're not about to confront an Officer to challenge him on his engine start procedures. John further instructed them : " Just get me going at about a fast walk. When we're going fast enough, I'll wave you all clear. And when you're clear of the aircraft, I'll just pop the clutch and be on my way. And thanks for the fast turn around ! " Six husky Marines quickly shoved the Super Sabre to a brisk-stepping speed. Green gives them an exaggerated arm wave-off. The Marines let the bird go, then warily stood clear before the pilot made the ' clutch move' he'd warned them about He didn't disappoint them. John momentarily jumped on both brakes . . dipping the nose to approximate ' popping the clutch.' Simultaneously, he secretly pushed start button . . that generates a BOOM along with a HUGE CLOUD of BLACK SMOKE as the F-100's engine whined to life. A chuckling Captain Green headed out to the runway's takeoff end, while six puzzled Marines with their mouths slack in amazement, appeared ' pinned ' in the smoky wake. -------------------------------------------------------------------------------- Gas prices getting you down?

Aviation is proof, that given the will, we have the capacity to achieve the impossible." - Captain Edward Rickenbacker |
