So you are with the boys having a few beers planning this trip and are feeling brave then?  Lets see how brave you are strapped to a drunk local guy* who used to be special services agent in a Soviet era plane that probably hasn’t been serviced since Lenin was a boy. 

You sort out the insurance and we’ll sort out the transport to the airfield, plane & equipment hire, tuition and the drunk local guy

*Note - he might not actually be drunk at the time of take off.
