At least 5 times. The first time I showed up, a SAM surprised me (and the JTAC ;) ), my other loss was a crash into the ground and I once lost part of my electrics (don't know why…). The rest of my landings were just rearmings.
I've fired hundreds of rockets, a dozen S-24B rockets (WOW!), a few gunpods and I screwed up a few bomb deliveries.
It was very fun and something I couldn't do without a proper human JTAC since you can't see shit with your Mark I eyeballs at 5000m.
