Was out today with my son JJ and his two stepsons.  Put them up again on a trainer of sorts to make sure they knew what the handle was for.  Then we started with the Streaker and Aaron first.  JJ is the coach in the middle and I am pit man.  Then it was Eaon's turn.  After several sessions of flying solo and an engine change on one plane it was time for two up.  A lot of work to pit two planes at same time.  In no time at all Aaron was doing good.  He is a fast learner and was getting plane around for pits stops.  Now crash was a different story when it came his turn for two up.  Two broken planes and a new nick name.  As I told JJ,  Eaon was probably getting tired.  Almost three hours in 80+ degree heat and not that much flying time before hand.  Watch out for them in Denver.  DOC Holliday
