I don't have the appropriate sectional to hand; can one fly one's cessna over the storage yards in the US? Must look interesting from above.
All of the US airliner storage locations are public use airports/airfields, some are tower controlled, some not. As long as you comply with rules of the air and/or tower instructions, yes they can be overflown. The military storage site at Davis Monthan, AZ is a different matter of course!
