Yes, definitely jet engines. My parents used to own a small business which was neighboured by a model aeroplane enthusiast. You could always tell (hear) when he was fiddling around with his jet engines in his back yard. Made me somewhat nervous actually, and it would also remind me of a Simpsons episode in which Homer builds a model rocket. You can probably guess what happens. :lol:
Closing laps of the '89 Indy 500. The way Emerson controls the car after they touch, at that speed, is beyond awesome! Good to see Unser Jr. at the end , while still on the track, complimenting Fittipaldi.
