Flying around the time of all the hijackings I flew with Qantas from Honolulu to Sydney. About 1 hour out of Honolulu the cabin lights went out. I mean ALL lights. There was an announcement. Assistance required in the forward cabin. This caused drink carts to be raced towards the back of the plane at break neck speed with staff running up the aisle. Then nothing. No announcement. We just sat in dark silence. Every so often a flight attendant would scoot up the aisle and I'd ponder whether to ask her what was happening. I figured she'd just say "don't worry about it, it is ok". I thought I was worried about it, that's why I was asking. I decided the ignorance is bliss and figured if we were being hijacked and I knew it, the real fear would kick in.
This went on for 15 minutes until there was an announcement by the captain "sorry folks, but we've had a fire onboard. It's all fine now and we'll continue on to our destination". WHAAAAAAATTTT. A fire and we were going to continue for another 9 hours instead of turning around to Honolulu.
I made it home safe without their being any other issues.
