Obviously the JASDF need to improve their "scramble for survival" times.....
. Surprising thing though is that they didn't have a SOP to do so when the tsunami sirens sounded - 30 minutes granted is not a lot of time but ought to be enough to get some ac (and especially helos) out of harm's way.
Brought back memories of tacevals in the 1980's and usually heralded endex.....
