And now for something different. This map uses the new add attribute trigger stuff to turn any rocket launcher into the airstrike, plus additional reload speed because the poor func_regen can't keep up. You can use stock or original (and it centre fires) and it should behave as the airstrike. If for some reason your weapon attributes don't change, which they should work pretty well due to where I placed the triggers, you can simply swap to a different launcher, count to 3, then re-equip the weapon of choice.
EDIT: Recent update has changed how attributes and other things interact. It seems that func_regen gets priority or something over any attributes which change health and ammo. As a result the extra ammo and reload speed triggers get overridden. You can still easily play offline if you have a regen bind or just bind mouse1 to "+attack; impulse 101" etc. as the regen ticks are not fast enough for the airstrike. Also gunboats are probably a good idea as you can do some ridiculous syncs.

There's bound to be alternate strategies to what I've done here, particuarly for the large vertical syncs 7 & 14 you can do angled syncs, shitty quads/quints or like what I did on 14, do a stacked crouched sync (which I think might be a bounce, and can happen fairly reguarly with this weapon).
Intended strats for bonuses:
b1 - speed pogo into a sync, resync high (basically jump 11 + 14)
b2 - sync and sync and..
b3 - wallpogo/catches etc. theres a few speedy options here
