I am reminded of the famous Blackadder sketch when Baldrick asks Blackadder for guidance when stepping upon a mine: " Well, Baldrick, traditionally one hurls oneself 200 feet into the air and scatters four limbs in all directions..."
Olster, Blackadder was actually addressing Lieutenant George whilst atop No Man's land in that scene, even though bird brain Balders was there too.
However whilst that isn't so important, the contents of the breifing received actually is. As mentioned by BDB how ludicrous is it to receive infomation about what to do in a rocket attack and then declare that safety of the crew is the number one priority.
The brief looks to be something that our heroes in the military forces might receive, you know the ones who fly aircraft equipped with chaff, flares, able to fly evasive manoeuvres etc. Not sure we checked that options box.......
