Thx keya,
I think the only real "hidden" field is the one up by A23 in the mountains.
In the update I've put the regular spawn points for A23 but the ones at an angle go to the hidden base.
On the very last day of the war May 3rd, John Glenn and Chuck Yeager were flying together in their P51s through the German/Austrain alps looking for that Jet base. It was a beautiful spring morning and they felt like tourists on holiday.
Hehe or something like that..
.. Glad your enjoying the map
