Discussion about flying into Mexico from the US, but not landing.

Wondering what the rules are regarding FLYING from the US into Mexico, but not necessarily landing.

Can someone point me in a direction for some guidance? If I wanted to take off from a US airport, fly down to a Mexican airport and overfly the field and check stuff out, or maybe just take a sightseeing trip along the coast and then fly back to the US, is that doable?
