@realtor_nancy :

@Andi7 : those are very rare these days. DHL exited the US market a decade or more ago. A few fly around without being updated paintwise

@ParksideRes : I was just showing the person who mentioned DHL what it would look like underneath. I would think the OP saw a yellow submarine as sandman clearly sees where he is at.

@ParksideRes : DHL domestic is gone but there is still the international express. But you're right, not a lot of those flights. My guess 1 a day at IAH, but not sure.

When I swim I see 3-8 planes in the 2 hours I am out in the water. A few helicopters also.
