Looks like a great museum, but what a shame about the ugly barriers. I much prefer museums that allow visitors to actually walk 360 degrees around the aircraft at close proximity - the F-14 and F-35 look pretty closed-off.
Maybe we shouldn't have done it, but we climbed up the A-6 at the Naval Air Museum once after having lunch at the Cubi Club Restaurant. I was with an a prior A-6 driver and he wanted to show me something in the cockpit...
No one in a volunteers vest seemed to mind.
