Sorry if this has already been discussed (I had a quick search then got bored) but is it possible that the pallet of food that was dropped on the island was intended for the Losties.
I have just been watching S.O.S when Rose was putting cans of vegetables onto shelves and thought that if the food was intended for whoever is supposed to be in the Swan then they are very large cans for 2 people. I know they are most likely to have a long shelf life but surely once they have been open you would want to use them up otherwise an open can will take up room in fridge or need to be transferred to some other container as otherwise the food would just gather dust. The cans Rose has will be must more suited for feeding 40 plus people and 2.
It was for the two man team in The Swan, they make drops every 6-8 months according to the blastdoor map.
That's what the lockdown was for, restocking.
The logistics of dropping food in such a remote location (the fuel, the transport, etc.) means that when you make a drop you drop as much as is possible, they probably dropped more than was needed for a two-man team and there was probably stuff left over, but it makes sense that they just dropped a crapload of food rather than enough for a few months.
Who knows, that pallette may be what six to eight months worth of food for two people looks like?
I Imagine if you piled up the packaging to everything you'd eaten over that period of time it would be pretty big.
i also just realised the apollo bar kate ate must have been out of date. they crahsed on the 22nd of sept, the 1st season was about 40 days and the bar expired on the 23rd of october
