Not nearly as bad as ending up crashing into an attic and making
international news. Still haven't seen an NTSB prelim for the guy from
Connecticut.

Tried to start his electric low over a high-density urban area, got
nothing but grinding sounds. Too low even to fire the ballistic chute.

Very poor flying technique, and I'm sure we'll see lots more of it as
FES becomes more prevalent. The OP's obsession with startup time is a
good indication of that.
