Fortunately, jet fuel is hard to ignite. Yay for that.
Okay, get everyone who will listen to move some 100 yard or so away, finding a good clump of trees with adequate drainage. Tell whoever will listen to move anyone who can't move themselves.
I'm going to ignore the type A assholes for the moment unless they are deliberately hindering anything I do. If they are, I'll figure out something. Go fiind food, look for a road, whatever. There's any number of ways to do this, but it's doable. Hell, I organize 300 odd hippies once a year to put on a festival, and I'm the only non "hippie" organized person to handle the logistics.
*someone* on the survivor list will have at least a first aid course, and probably more. Whoever it is does triage. Any adult or older children who can are going to be assigned nursery. (Having something todo is important) Anyone willing to do so is going to go with me at that point and find 1: lighter 2: cutting tools 3: shelter pieces. Anyone else who isn't finding themselves a job is policing the campground and making bedding piles of needles or whatnot.
1: something will turn up. If nothing else, one of the crew will have matches. Heaven forbid, but I can do the bow drill if it needs doing. My luggage will have a firesteel and a decent knife or three anyhow.
2: axe in cockpit, knives in luggage. this is going to be important, I' not just feeding the forum topicality. There's a lot fo shelter to build and so on.
3: wreckage, baggage covers, whatever. Not the lifeboats, they have another use.
Once I get fire going, everyone is going to get that animalistic feel better going on. Then it's water. - lifeboats are the collection devices of choice.
By this time the plane would either have burned big (unlikely, actually), or it's going to be safe to comb the wreckage. But I also assume it's dark. Raid the galley. no sense rationing food, get everyone anything they can eat now.
type A assholes are going to be dealt with at this time. Compromise is preferable, but I'll do what I need to get through, including lie about background. (E5? try O3. Whatever it takes to back them down). When possible, I'll enlist them to Do Something.
Explain and get concensus on the first rules: 1: no negatives. This is not the time to dis, gripe, moan, or backstab anybody. NO NEGATIVE TALK about ANYONE. 2: Doing anything is going to be better than doing nothing or arguing, so we all need to DO. 3: explain basic foragables and food sources, water collection, instill some confidence. 4: explain the huddle- sleeping in groups makes it really hard to freeze if you get all your clothing and fabrics and brush together and stay close. 5: fire watch. This first night, just keep it going and keep it big. Drying wood needs to be cycled.
