My wife saw Tanker 10 as we drove through Tehachapi. See said "Isn't that kind of low?" In fact, according to news reports, it had just barely cleared the ridgeline and had actually clipped a tree. That had to be a scary ride. The little chaser plane followed it while it dumped the rest of its load at altitude.. guess it was checking for damage (although the news photo showed very minor damage, so maybe it only clipped the very top of a tree).
