How about a trackside Airfield?

My brother was a co-pilot on a Martin B-26 Marauder during the final days of WWII so I put together a Revell 1:48 model for his birthday. Would work nice in O gauge but that thing would have dwarfed an old Lionel engine; it was NOT small.
A 1:24 model would be twice as big. use up 8 times the volume and 4 times the real estate; of course, it never hurts to think big.
