Candle--absolutely.

When in different environments, the EDC or BOB kit needs to be re-adapted to the situation. While I don't normally carry emergency candles on me, my travel kits (a five gallon bucket) does.

I haven't flown in a small aircraft in years, but regardless of the transportation, (air, land, sea) I can figure out what I may need in a ditch.

Sounds like for the most part they did the right thing. As a non-aviator, I leave that to those with experience. As someone who tries to be prepared, I'd have had that suit on to start the trip (at least legs in) and my kit on my person with a BOB close.
