The Saab looks like a blast to fly, as it's light and the canard gives it some cool attitude control. It's like the
Concorde in miniature. (Imagine the Concorde with drop tanks and huge missiles underslung. LOL)
Israel has modified their/our latest stealth fighters to standards Iran can only dream of. Basically they pull back the software safeguards on our standard flight envelope and let the guys go a bit cowboy with the gear.
They
might loose a couple more guys (and billions in hardware) ripping metal, before they tune in to the tactics of an envelope we don't try to fly. The software will track what they've done, so they'll have test data, & (hopefully) they'll find any problems like cracks from overloading or mechanisms that bind under high forces.
Risking hot-shot test pilots isn't a thing done in trivial circumstances; yet, trivial theirs are not. But they are really extending our test program of the aircraft where we haven't gone. The capability could come with a big reliability factor.
They teach every pilot to never fly at 10/10 or 100% of your craft's capabilities, except in dire emergency. Well we don't really know the ultimate capabilities, but the Israelis will get us closer.
In the end, we surely don't want to see Israel shoot Saabs or vice versa.
Much better to see IRGs bailing out of their flaming Russian death-traps.
