Hi fellas
Went up for a spin in a Tecnam Sierra from Boeing Field just south of Seattle this afternoon. On the way back on long finals we were told that "you've got a heavy cargo aircraft, one of those big scary green ones coming up behind you and will be passing you on short finals landing on 13R" we were heading for 13L so my friend elected to do 3 orbits and wait for the Boeing 747LCF (large cargo freighter) and its big wake pass us by.
Just 4 weeks ago this same cargo aircraft landed on 13R as a 172 was on short finals on 13L and the wake carried across the field causing the Cessna to almost crash, it recovered at 200ft thankfully.
Anyway, it was an awesome sight to see that new cargo aircarft come out of the low cloud above us and pass us by, still in the same green primer scheme. Its call sign was '747 experimental', a british accent on its radion too. As far as I know its just finishing its certification and who knows could have arrived at Boeing field for the paint shop.
Just thought I'd share this.
By the way the LCF is as ugly as it is in the photos
