I can see two scenarios here:
-
High school marching band is armed to the teeth because they are sponsored by the NRA.
(You said “storm the plane”. You didn’t say “get the hostages out unharmed”.) -
High school marching band is really, really bad. After two hours of heavily distorted versions of popular tunes from the hijacker’s cultural background they give up and beg for mercy.
However, some of the hostages sue the band for damages.
