Hell I did too many smiley faces and It didn't let me post my reply....well it was probably kak anyways..... so here we are again sans little smiley faces.....
With the sams you not going to see it unless you got good eyesite or wearing your superman outfit..... last sam that was seen was from the cockpit of the following aircraft........all they saw was the smoke trail as it went wide.....
It does very much depends on the flavour as to where you going to be safe.... when you below 10,000 AGL the shoulder launched sam 7 or stinger, but you gota see what you shooting at first, wait for the thing to start growling, then hey presto ! pull trigger and all going well.....bye bye bad guy.....however if you point and shoot in the general direction it going to go whizzing past and scare the sh#t out of anyone who see's it.....
The next one they have is the supersonic telephone type, usually truck or fixed site launch, however the sting is its radar guided and longer range.. they say up to 15,000 AGL and it will still get you, dependant on model, can even be higher... and if you lucky enough to see it and try some of the fancy stuff, i has a proximity fuse, so it'll think hey close enough....BOOM !!
want to see what they look like.... after take off RWY 23 FNLU climb straight ahead , look out the left hand window at the end of the runway... small herd grazing.....
There is another to beware of..... thats the former Olympic Clay Pigeon shooter... he is rumoured to have taken out a AN12, Boris got careless out of one strip, figured with his liquid Kevlar would climb on track to destination.... No Fu*&in fais mal..... so no evasive manouvers.... bang !! no suprises there......taken out with nothing more sophisticated than an RPG7.... far fetched maybe...but Boris isn't around to tell the tale....
The last one is the AA guns... they do have them but generally the are never swivelled above the horizontal...to much hard work... they used in the Urban theater to shoot though the barn door to get at the guy on the other side...easier than out flanking him...but if pointed skywards....good to about 10,000 AGL
All of course open to rumour, speculums and correction.....so going to have a beer now to cool off the brain.....
