We're not debating for points here. For the purposes of the discussion, the link proved me right. You can claim the link proved you right just as soon as you can show airlines running routes with a 747-400 over 65,000 feet. Until then, you're just tilting at the windmill.
Anyways, I said we can now move onto question two since you accepted (by failing to disagree with the data therein on the wiki link) that for airlines traffic, as the aircraft climbs, the speed of sound drops.
This is true, but aircraft are also designed to to work in conjunction with other speed indicators, notably that readings called out by air traffic control, ground speed indicators and GPS, at least for knowing their actual speed over land. For aircraft performance concerns, the important reading is the indicated air speed, and while there MAY be small errors between indicated air speed and actual air speed, they aren't going to be so drastic that the pilot isn't going to notice his plane shaking apart well before he reaches mach 1.
you say sound decreases in altitude, but your own link confirms this is just you cherry picking from a limited understanding
https://en.wikipedia.org/wiki/Speed_of_sound#Equations"However, there are variations in this trend above 11 km. In particular, in the stratosphere above about 20 km,
the speed of sound increases with height, due to an increase in temperature from heating within the ozone layer."
Send an angry pm to wiki, i'm sure they'll change it to agree with your military bias of the state.
And keep dodging every question i ask, its clearly a sign of your emotional immaturity.
