This goes back to WW1. Firstly they used a metal deflector plate to protect the propellor. Then someone, I don't know who, invented a synchronised method of allowing the bullets to pass through it. By WW2 most machine guns were wing mounted. The Me 109 had a cannon which fired through the very centre of the nacelle.

There were 5 different beaches that were attacked sepately. Some managed to break through very soon after landing the beach was right next to a town. The American beach took 5 or 6 hours to break out.
Army style jackets are a big trend right now, therefore they are available from a very wide variety of retailers. They can be found through stores like Nordstrom, Overstock, and eBay.
Distracting the attention of the garrison commander by ordering a cavalry raid right down through the state of Mississippi, while Grant managed to get his men across to the East bank of the river, unnoticed.

Propellers are either "Left Hand" or "Right Hand". When the propeller is viewed from the blade edge or its side, the blade is angled upward to the left (Left Hand) or upward to the right (Right Hand). See illustration. enlarge Regards, Mike Leary misticmike@googlemail.com
The propellers move it forward and the rudders guide and steer it left and right
The Earth rotates on its axis, and it revolves around the sun. Rotation is the same as spinning, and this is what a top does, or a coin that has been set spinning on its edge on a table. In the case of a coin spinning on its edge, the 'axis' goes right up through the flat dimension of the coin.
To counteract the the right hand tourque produced by the clockwise rotating engine
Yes, you could do that.

The Lockheed P-38 Lighting had supercharged 12-cylinder Allison engines fitted with counter-rotating propellers to eliminate the effect of torque. These were left and right hand engines and maintenance was more difficult because a left engine could not be used in place of a right engine.
The Titanic had 3 propellers. She had 2 wing or outer propellers each with 3 blades and 23 feet in diameter, and 1 center propeller with 4 blades and 17 feet in diameter. All propellers were made of Bronze.
You can buy exercise bikes that specifically cater to spinning. The model should have the information right on the box but if not, ask the store sales associate for help.
that depends on the way the propellers work. for example, if the propeller on the right has some problem and works a little less powerfully, the shuttle moves towards the right side. but it is made sure that the propellers are working with equal power to maintain the shuttle in equilibrium. in the shuttles with single propeller, it mostly projects straight in the direction in which it is launched:)
