Aircraft engine manufacturers construct aircraft engines, and maintain the engines when faulty.

The invention of steam engines to drive factory machinery allowed manufacturers to build factories away from running water.
The engines are running at slightly different frequencies, so their sounds combine to make beat notes whose amplitudes vary quickly.
The Environmental Protection Agency (EPA) is an example of a regulatory agency. The EPA regulates things that have to do with the environment. One of these is the amount of emissions that is allowed to put into the atmosphere by vehicles. Manufacturers try turn out low emission vehicles. The cleanest running vehicles outside of solar cars are natural gas vehicles.
A diesel vehicles does not need to be running. A diesel ignition in a Diesel engine comes from compression and not spark.
The rise of VAT and oil prices are not good, this delays the fuel ignition as people are waiting longer before going to a fuelling station to fill up their vehicles there for this problem is ruining the ignition of our engines as the vehicles are running on the sludge at the bottom of the fuel tanks.
there are many engines in this parking lot.
In general, no. IF an aircraft had a headwind that was faster than the stall speed, it could in theory be motionless in regard to the ground- but the stall speed for most 4 engined aircraft is about 150 knots- that would be a VERY strong headwind. Flying into a hurricane might do it.
