Max groundspeed you have ever gotten?

[Mmmmmm Burritos]

I saw -25 knots GS (yes Negative) in a Cessna 152 once. I asked approach what my groundspeed was and he couldnt even see me

419 KTS in the Mu-2 at FL270 from FXE-CDW had 110kts on the tail over North Carolina

saw 791 kts over the deserts of Utah this past summer in the back of an F-16

635 kts Roswell, NM to Nashville several years ago. 1:37 min in a Lear 25

Must be the aliens in Roswell giving you an extra push.

I was sitting around the FBO Monday waiting for pax when I picked up Robb Report or some other "stuff you cant afford" type magazine. There was an article by the SR-71 pilot who wrote "Sled Driver".

He tells a story about a training mission over California where they hear a guy in a Cessna ask ATC for a groundspeed. They tell him 92 or something like that. Then a guy in a Bonanza (or similar) asks the same, they tell him 160. Next a cocky sounding guy in an F-18 asks. ATC tell him 615 knots. These two Blackbird drivers decide this guy is being an arrogant a$$ and decide to nip it in the bud. Naturally, they ask for their groundspeed, and the controller tells them, without missing a beat, 1,905 knots! (I cant remember the exact #, but it was in that region.)

As for myself...428kts in a DHC-8 TLH-CLT in the low 20s.

I was flying in the area when I heard Grand Canaris Control asking a TU-154 for Mach number. It was given .95 and for ground speed 735 kts.

Climbing out of Japan the other day we saw 210kts. Amazing it was very smooth, we were on our way to Guam.

LMAO

169 kt GS at 12,000' in a C 172 SLC-BOI.

457kts @ 23.0 between LIT and CVG in SA227. For once I was in the right place at the right time. The controllers where said that was the best they had ever seen for a Metro.
