I seen a light with a red blinking one, this aircraft flew through the area quickly, but made no sound. I am looking for the logical explanation for this before I jump to conclusions.

There are a lot of reasons why a plane might seem like it is not making any noise. The first is distance. If the plane you saw was a passenger jet at altitude, it was several miles away from you when you saw it. (35,000 feet altitude equals over six miles)
If the plane was a private aircraft, it was still probably over a mile (5,280 feet) away, and it would not be terribly loud to you.
Another possibility is that the wind was blowing. Wind plays a major factor in how and what direction sound travels. If the wind was blowing from you towards the airplane, you might not have heard anything at all. If the wind was blowing from the airplane towards you, you would have heard a great deal more noise.
Yes, gliders can fly limited distance without the use of an engine, but that is not common.
Yes, a plane traveling over the speed of sound (Mach 1+) would not make any sound, UNTIL it passed by you. At that point, the sonic boom would have been extremely loud. Aircraft are not allowed to fly over Mach 1 over land because the sonic boom can literally crack windows on the ground, even when at very high altitudes (60,000 feet/11+ miles).
Yes, the B-2 Spirit and F117 stealth aricraft are designed to emit very low levels of sound (when seen from certain directions).
Best guess, without knowing a lot more about the conditions, is that it was a combination of wind and distance that made then plane sound quiet.

Gliders of course are very quiet. Any aircraft can be quiet if conditions and the A/C itself are right. Often Airliners at Crusing Altittude can't be heard from the ground. Other times they can depends on conditons. Also the drive in the past few years have been for quieter A/C.

certain it has develop right into a faith and Al Gore is the pope of the cult.imagine of ways a lot funds particular communities will make off of the hype.imagine of all that authorities funds going to "analyze".as well there is in common words a lot you may do ,after all whoever controls the elements controls the international.worry is the perfect political motivator. climate change is part of the nature of the planet.worry-free experience is to have sparkling means yet till there's a dollar in all of it that occurs is communicate,communicate and extra communicate.authorities regulations,fines and consequences(gotta get that bailout funds someplace) We truly pick sparkling air and water .i'm the unique recycler and that i do not waste means clone of many human beings.i exploit means and do not flow for the "guilt" vacation of doing so. I have a subject matter with Gore the guru who flies round a gas guzzling jet.So does Queen Pelosi who opted for a better one to fly lower from side to side to California.keep in recommendations her announcing she needs to maintain the planet,yeah she flies we walk.we may be able to all commence through utilising the hot means saving mild bulbs. Oh I forgot they're those with mercury in them.Oh,nicely sounds like a sturdy theory on the time. i wager you all heard that some genius baby-kisser wanted to tax cow farmers for any that personal better than one hundred for emitting "methane gas" yeah that is authentic.will we bottle it somewhat?Or on 2d idea deliver some from the bull to that baby-kisser as he's popular with the B.S. even as he sees or smells it.

You saw a Glider, an aircraft without an engine, it flies in thermal air currents.

glider. nature makes some too. lol man made aircraft. sorry. if it was a plane traveling at mach 1, you still wouldve heard it. after it has already passed by though.

Lots of light aircraft in Germany have exhaust pipes and silencers like a car, they are as quiet as a car. In the US and UK they run without exhausts. just a silly little stub pipe which is why they are noisy.

the aircraft was traveling at or beyond mach1........it ac hived this speed long before it entered your air space......that,s why you couldn't hear it!

Eastern Airlines used to call their planes "Whisperjets"
