There was never any doubt about the first place I would fly to in Flight.  It had to be the Mauna Kea Observatories.  I tried this in the Stearman (I just cannot bring myself to fly that butt-ugly float plane) and had a lot of trouble getting above 13,000 feet.  Anyone know what the ceiling is in a real world Stearman? 

Instead, I opted for the Vans, seeing as it's right up my alley for the planes I like to fly.  What I wouldn't give for a Cessna 182!  I'd better shut up before MS hears that and decides to charge $50.00 for one...
