Not an expert, but a homeowner. MOST gas fireplaces (and other appliances) have a flame sensor- frequently in the form of a thermocouple. Intended to prevent gas from flowing when there is no flame present. If the thermocouple is bad, it will shut off the gas flow even when a flame IS present. It may look like a small rod that is in the flame of the pilot light. I would REALLY hand this of to a professional gas repairman. The cost of having this done right is FAR less than the cost of doing it wrong.
The first American pilot to exceed the speed of sound in an airplane was Chuck Yeager.
The first flight at faster than the speed of sound occurred on 14 October 1947. The aircraft was the Bell X-1 and the pilot was Captain Charles Yeager.
More drag is created because the molecules cannot "hear" the airplane coming.
Jacqueline Cochran flew an F-86 Sabre fighter plane in 1953-becoming the first woman to fly faster than sound. She outdid herself in 1964 when she flew faster than twice the speed of sound. In total, it is believed that Cochran set more than 200 records during her career.
The airplane becomes more difficult to fly because there is more drag from air molecules
To me it sounds like your pilot light on the fireplace is out. That could happen from a strong wind coming down the chimney or a strong breeze in the house from a fan. Check your pilot light and be sure to have the gas off before lighting the pilot light if it is out.
The I in pilot has a long I sound, as in the word pile. The O has a schwa sound.

Charles Yeager was the first person ever to pilot an aircraft beyond the speed of sound.
Chuck Yeager is credited with being the first pilot to break the sound barrier on October 14, 1947 in a Bell X-1.
The I is a long I vowel sound as in pile. The O has a schwa sound.
Sound Check - 2011 Pilot 1-1 was released on: USA: 30 July 2011
No, the pilot does not hear the pressure wave that causes the boom when he is going faster than the speed of sound.
The "i" in "pilot" has a short vowel sound. It sounds like "ih" as in "sit."
