hey i just did somethin really fun i dunno if anyone else has tried this before but neh ill say anyway just so whoever else has got this can try it out:
from the old air strip i unlocked in the missions, i took the old spitfire type plane n flew it over the area 69 base which got me immediate 5 stars wanted level ( at this bit you have to dodge the missiles they fire at u, which is a pain in teh ass when ur not goin fast enough etc etc )And then waited till the 2 harrier jets catch up and then you can turn on em n shoot it out
real fun for me lol i dun all the missions so findin new stuff to do is always fun, its sometimes difficult to dodge their rockets cos ur plane is alot slower than the jet but its cool doin the old circlin game n gettin on the inside of em n shootin em down like u see in the old war movies
I got both my wings shot out one time so tryin to control the plane was a bitch n i flew into a police helicopter n blew up
its a good laff tho i suggest ya have a go

Ezekiel 25:17
The path of the righteous man is beset on all sides by the inequities of the selfish and the tyranny of evil men. Blessed is he, who in the name of charity and good will, shepherds the weak through the valley of darkness, for he is truly his brother's keeper and the finder of lost children. And I will strike down upon thee with great vengeance and furious anger those who would attempt to poison and destroy my brothers. And you will know my name is the Lord when I lay my vengeance upon thee.
