Hi John,

The actual meteor (trail) I saw was very fast and lasted only 1 second.
A train was left behind (as Lew explained) that remained visible
for 8 minutes before completely vanishing from high altitude winds.
As for Iridium satellite flares, I don't think they can be easily
confused with slow meteors, especially after seeing a number of both.
Iridium flares have a gradual brightening until peak and a gradual
decrease until they disappear. Satellites are usually much slower and
last much longer than most meteors. Meteors will often have quick
flares, subtil changes in velocity and/or wakes or trains that sets
them apart from satellites.
