HomerJ,
You are right, being a prop captain only forces you to start as an FO.
When you apply it might take a long time before they let you go to the interview and assesments.
Then you will have to swim in the holding pool for a very long time with the others that have been waiting for more than a year.
If you are then offered a job then you have to wait a minimum of 6 months before you can apply for the upgrade process.
That's provided your 2 previous sims have been above standard in order to join the process.
If accepted for the upgrade process you then have to complete this which can take more than a year, as in the summertime the upgrade process is temporarily frozen.
If you pass then you have to join the pool for a command course which to my best knowledge consists of 150 people at the moment.
With 20 temporary commands for this summer and a command list that gets longer and longer for every day that goes by I predict a very very very LOOOONG time of waiting for you
