On my second solo at 300' the door popped open at the top and was flapping in the breeze-so if you are flying a PA28 (or whatever else for that matter) give the closure of the door a thorough testing once the instructor gets out.
This happened to me on second or third solo,I thought the airflow would hold it closed but of course the negative air pressure above wing would hold it open.
I continued flying in blissful ignorance,but the CFI said I should have landed back at the airfield ASAP.
Anyway the top latch on the PA28 is horrible and should be checked for complete closure before any flight.
