Interesting F-100 story....

When ignited by electrical current, the expanding gas from the black powder-like pyrotechnic cartridge drove a starter turbine which brought the engine up to a self-sustaining rpm via a drive system. This eliminated the need for heavy and bulky ground starting units, but the starter cartridge spewed out a characteristic dense cloud of choking black smoke, which was often mistaken by inexperienced ground crews for an engine fire. Good story. Cartridge starts were not an F-100 exclusive. No, they were also used on the licence built English Electric Canberra - Martin B57 - and the smoke generated, very dense and very black, was amazing - enough to put the fear of God into you, if you'd never seen it before. Ricardo And we used them exclusively at Korat during my F-105 tour for every start, every day. We also used them on nuke alert for the F-4. Lots of airplanes had cart start capability. But, gotta give credit to the Hun driver for some fast thinking, creative fun and leaving those transient alert types with something to think about. (Seriously though, I've got to figure that anyone who was allowed on the TA ramp to fuel, turn and launch jets would have been hard to fool. Makes a good story though.)

Interesting F-100 story....
Carts starts. I was at Bitburg when the Air Defense Zulu alert F4E got
a hot scramble. The favorite scramble start routine then was to fire both carts at once and move both throttles forward for a simultaneous start and thus get off quicker. Alas, one cart did not fire. The crew, full of adrenalin, did not realize this until well past normal liftoff.(Usually about 4000 feet of roll). Being loaded with 3 external tanks, the AC decided to lighten ship and punched them off, thus getting airborne well before the end of the 8000 foot runway. He airstarted the dead engine and pressed on. This resulted in an absolute veto on 'double bang' starts and renewed emphasis on checking the engine instruments before takeoff. And an 'aw s--t" award to the crew. Walt BJ |

Seriously, the real problem was the head-up-and-locked nose gunner who didn't watch the engine gauges after hitting the switches as well as the WSO who didn't catch a clue-bird. Failure to make 1000 foot line-speed would have been another indicator. There's really no solution for aircrew screw-ups. Related story: Sitting Victor (15-minute) alert on an ORI at Incirlik, got scrambled with a "shape" (not a real bomb) for an "elephant walk" (all the alert birds simulate a launch up to the arming area and runway but don't fly). One cart fired, other didn't. Taxied with one engine and any time I saw an IG type watching would jazz the throttle to give me some momentum taxiing past so that he wouldn't notice the slack nozzle on the dead engine. Poor taxi technique, but it looked like an "up" airplane as far as the inspection was concerned. If you ain't cheatin' you ain't trying.
