Multi-billion is a bit high, even for modern planes. You basically have to crash a B-2 bomber to get there. Which has, of course, been done.

Incredibly expensive plane to put in the air. Recent ISIS fighting article claimed 100 hours of maintenance for every hour of flight.

Well, to be fair, this was back in the 70's or 80's, and the little Macchi back then would have had a 'fly away' price from the lot at probably about $1million - but still, more than a lifetime's wages back in the day, even for an Air Force flight instructor! :D
