Of course its a possibility, the Article itself makes provisions to extensions to the negotiations. Realistically though any extension to negotiations will be a matter of a few months if they think there is light at the end of the tunnel by next march. if the wreckers have made any deal impossible, we will all know before the need for an extension is considered.......then we will just leave with no deal.
Crashing out in March with no transition and all that follows is more than a distinct possibility now. I wouldn't say that a deal being made is impossible though, anymore than I would presume to know the length of any possible Article 50 extension. Further concessions or not, if a deal was agreed and then subsequently rejected by parliament, it would get most interesting as to where this goes next, hence the Article 50 extension coming into play.
