QUES: Hazards to aircraft include debris, nesting birds, and reduced friction levels due to environmental conditions such as ice, snow, or rain. Part of runway maintenance is airfield rubber removal which helps maintain friction levels. The fields must be kept clear of debris using cleaning equipment so that loose material does not become a projectile and enter an engine duct (see foreign object damage). In adverse weather conditions, ice and snow clearing equipment can be used to improve traction on the landing strip. For waiting aircraft, equipment is used to spray special deicing fluids on the wings.
What is one part of runway maintenance that helps maintain friction levels?

ANS: airfield rubber removal

QUES: At the Battle of Mars-la-Tours, the Prussian 12th Cavalry Brigade, commanded by General Adalbert von Bredow, conducted a charge against a French artillery battery. The attack was a costly success and came to be known as "von Bredow's Death Ride", which was held to prove that cavalry charges could still prevail on the battlefield. Use of traditional cavalry on the battlefields of 1914 proved to be disastrous, due to accurate, long-range rifle fire, machine-guns and artillery. Von Bredow's attack had succeeded only because of an unusually effective artillery bombardment just before the charge, along with favorable terrain that masked his approach.
What did General von Bredow lead a charge against at the Battle of Mars-la-Tour?

ANS: a French artillery battery
