Thanks Steve.  I am a big Johnny Cash fan since my childhood.  I like to see
baritones make it rather than all the tenors and such.

I recall my calcs from a long time ago that from a weights perspective a
feet first landing makes sense on a first stage under some circumstances.
It weighs more than a parachute-into-the-sea recovery, but if you plan
multiple launches and want fast recovery time, you can give away some first
stage performance in exchange for that cool feet first notion.  Besides
that, to those of us who grew up on Rod Rocket cartoons, it just looks cool,
and is far more dignified than having to be fished out of the sea.  Please
tell me I am not the only one here who loved Rod Rocket and Joey.
