I don't know if a Zippo would set off C4. I think our soldiers in Vietnam used to take small blocks of C4 and light them, and then they would slowly burn, rather than explode.

No, but I bet it'd ignite the heck out of the detcord that they mentioned being in the shoes, which would then detonate the C4. Very scary situation. Kudos to the flight attendant and passengers.
