[QUOTE="kristianjohnsen, post: 42265, member: 441"] Re: Airplane faster than a speeding bullet? Bennet. I might be reading your post wrong, but just to be clear: Speed of sound changes with altitude due to the changed density of the air. Extreme example: sound in water=super fast because of water being a lot denser than air in general. BTW, most jets will be unable to reach their maximum speed close to the ground. 1,1 mach is however typical for a low-level bombing run by a fighterbomber, as I understand it. Regarding shooting down planes with hand guns (it does happen in war-time): I think the more usual scenario would be that a whole platoon of guys spot the plane coming and just fire away and empty their AK-47s right as it's passing over, and a few get in a lucky shot. WWII tail gunners apparantly had a little math to do, also, due to the guns behaving a lot differently than when firing straight forward. All this talk of guns and shooting made me forget my manners: Jack, my condolences to you and your family. [/QUOTE]
