High risk, high reward.
Jets cost $120k (high risk) and can be very 'OP' and can get you loads of kills (high reward) but all it takes is a decently skilled player to shoot down a jet...I understand it could be annoying to die but honestly play it stealthy, get to a gun store, get a AA launcher and fill a quad with AA missiles go hide and when he flies over take him down. Not hard.
Yes, I myself have died many times to Blue Eagles jets...makes my blood boil.
