 \begin{document}
-This is an introduction.
+\subsubsection*{Context}
+\begin{itemize}
+    \item Designing Emergency Checklists is difficult
+    \item Procedures in checklists must be tested in simulators~\cite{nasa-design},
+      which usually means trained pilots test it, as the tests need
+      to work consistently~\cite{manifesto} (making sure it's not lengthy,
+      concicse and gets critical procedures)
+      	\lfcomment{Testing for what? What's the baseline? I guess you will need some kind of evidence/argument that demonstrates that with and without the checklist results are markedly different. }
+    \item Checklists are usually carried out in high
+        workload environments, especially emergency ones
+\end{itemize}
+
+\subsubsection*{Problem}
+\begin{itemize}
+  \item Testing procedures in checklists are often neglected~\cite{nasa-design}
+    \item There are some checklists that may not be fit
+        for certain scenarios - e.g. ditching (water landing)
+        checklist for US Airways Flight 1549 assumed at least one engine
+        was running~\cite{AWE1549}, but in this scenario, there were none
+         \lfcomment{What check lists and what scenarios?}
+    \item Some checklists may make pilots \enquote{stuck}
+      - not widely implemented, could be fixed with \enquote{opt out} points.
+      e.g. US Airways 1549, plane below 3000ft, could have skip to
+      later in the checklist to something like turn on APU, otherwise plane
+      will have limited control~\cite{AWE1549}.
+    	\lfcomment{Yes, or might make them ignore the checklist. What criteria does that?}
+    \item Checklists may take too long to carry out - Swissair 111
+    	\lfcomment{Yes. See Checklist manifesto test}
+\end{itemize}
+
+\subsubsection*{Rationale}
+\begin{itemize}
+    \item Test checklists in a simulated environment 
+      to find flaws in checklist for things like
+      \begin{itemize}
+        \item Can be done in an amount of time that will not endanger aircraft
+        \item Provides reproducible results
+        \item Procedures will not endanger aircraft or crew further (Crew refering to Checklist Manifesto with the cargo door blowout)
+      \end{itemize}
+      \lfcomment{Again, explain testing against what}
+    \item Results in being able to see where to improve checklists
+\end{itemize}
