Abstract: Im not trying to promote the sale of any particular product - nor do I wish to disparage any method or equipment, but . . . Im happy to report that after experimenting with various underground projectiles for almost 20 years, at Long Island Lighting Company (LILCO), we feel that we have finally found the one that really does the job. Its successful operation with a small crew size has produced dramaLic savings over conventional methods on small boring and jacking assignments. We first became interested in missiles in the early 1960s and after numerous attempts gave up because of lack of Success. The missile either deviated up, down, or sideways or got stuck enroute. We finally gave up on missiles when we got one stuck under a state highway that couldnt be pulled out - even with a bulldozer!
