My source was not wikipedia.Student wasn't the only one who planned Crete. I love how you jumped onto Wikipedia in the 5 minutes since my last post. Now go read who else was involved from within the Wehrmacht in planning that operation, including those who outranked Student.
Now tell me which one of them outranked Kesselring and would have been able to pressure/bully him into conducting an operation in a way he didn't want to do it.
There was one person. His name was Rommel.
Rank does not always decide who does what.
Student planned the paratoop opertaions in crete. the Paratrooper were not even part of the army. they were outside the normal chain of command.
