I mentioned both radar and heat.
If MANPADS are heat seekers, okay.
Some versions of stealh try to lower
their heat signatures, e.g.,
hide the jet engine output from
the ground by an extension of the
part of the plane below the engine
and mixing the jet exhaust with cool
air. For the F-117, can get a
little view of its engine output

Looks like they tried to hide the exhaust heat.
