There was no wind and the air temp was dropping. it was the low 70s to high 60s. How does that change with the speed.
I understand the colder air has more air molecules deal... but does that increase the speed at which the sound travels?
Oh.... and they were taunting.... But not just lower.... Inverted... Inverted... My Grand mother could fly faster and LOWER inverted!!!!
This side of flying is truly exciting!!!!! I wonder how much more alive it will be with a PIPE!!!!!! [>:] Oh YEAH!!!!
The speed of sound is effected by density and temperature is one thing that does effect density. The Doppler program considers temperature/density to determine speed.
I say a prop strike is low enough. A tuned muffler or pipe should get you to around 130 mph.
