As I passed Flagstaff, ABQ Center called out traffic to me, a C130 approaching from behind at 12,000 feet. The C130 crew wanted to know how fast "the little guy" was moving. With the headwinds, I was making only 150 knots groundspeed. Even so, not bad considering I was working with only a single 260HP engine versus their four 4500HP engines. As expected, they soon caught up and passed me. Seen loafing by just under my canard, probably making only 200 or so knots. Even though it looks small here, it was quite a sight! Almost 100 long with a wingspan of over 132 feet - I should have offered to trade a ride in my plane for one in theirs!
