THAT would be fun on short final to a dark runway!

Dan,
The air temperature inside a wing at night in flight will never get
anywhere close to 140F, so it won't happen on short final at night...
plus, it would take at least 45 minutes to an hour even in a 140F
ambient for the unit to get hot enough to self-protect.

I can fore-see a mini-draft tube as an optional addition. :-)

John,

Actually that isn't necessary. Wings leak quite a bit of air in
flight, so there is always some airflow inside them. Even if there is
no airflow, our unit will passively cool in stagnant air. The volume
of air inside most wings is perfectly adequate to allow it to remain
at a reasonable temperature even if you are parked on the ground.
Once in flight, there is plenty of cooling so the unit will run even
cooler...
