Here is the latest cadet challenge:
On Saturday, eight flights-J,K,L,M,N,O, P, and R-are scheduled to depart from a small airport in Middletown. For safety reasons, no two flights depart at the same time, and each flight departs exactly once (duh!). The flights depart according to the following conditions:
Flight R departs at some time after flight L.
Flight K departs at some time after flight P, but before flight R.
Flight L departs at some time before flight K, and flight N departs at some time after flight R.
Flight J is the seventh flight to depart.
What is a possible departure order from first to last?
This is the first qualifying challenge for the prize to be awarded in June. This challenge will conclude 0730, Friday, 2 August. Good luck!
