During their mission planning, the crew measured the distance between a point that was easy to find and their intended target. As they approached the target, the crew could fly over the preplanned point, whereupon the WSO pushed a button that commanded the pod to look directly at the target over the premeasured distance.
Raytheon claimed the exclusive right to use Paveway™ as a trademark for selling LGB-related products. Lockheed Martin claimed Paveway is a generic term in the defense industry. Lockheed objected to Raytheon's registration of Paveway in opposition proceedings before the United States Patent and Trademark Office . [ 10 ]
A typical LGB model train on a garden railway layout.. LGB stands for Lehmann Gross Bahn - the "Lehmann Big Train" in German. Made by Ernst Paul Lehmann Patentwerk in Nuremberg, Germany, since 1968 [1] and by Märklin since 2007, it is the most popular garden railway model in Europe, although there are also many models of U.S. and Canadian prototypes.

A laser-guided bomb (LGB) is a guided bomb that uses semi-active laser guidance to strike a designated target with greater accuracy than an unguided bomb. First developed by the United States during the Vietnam War , laser-guided bombs quickly proved their value in precision strikes of difficult point targets.

Hornby Track-Master is a birds eye 2D Planning tool, distinct from Hornby Virtual Railway (HVR). HVR [ note 1 ] uses a 3D Planning Environment in which one can plan, build and test a layout. However, being released many years ago, it has fairly low quality graphics.
Too tight a 'crest' curve could result in the train leaving the track as it drops away beneath it; too tight a 'trough' and the train will plough downwards into the rails and damage them. More precisely, the support force R exerted by the track on a train as a function of the curve radius r, the train mass m, and the speed v, is given by
The notion was motivated by Thurston's train tracks on surfaces, but the free group case is substantially different and more complicated. In their 1992 paper Bestvina and Handel proved that every irreducible automorphism of F n has a train-track representative.
