When Ben Spies' engine exploded along the main straight whil🅺st running second in Sunday's Indianapolis MotoGP (pictu♉red), it caused some scary moments for those behind the Texan.

While Spies' Yamaha team-mate Jorge Lorenzo passed into second without trouble, the growing cloud of smoke around turn one caused major vision problems fo🧸r those next in liꦯne.

"After Ben's engine broke I couldn't see anything An♏d I couldn't see where Ben was," said Andrea Dovizioso, who moved from fourth to third after Spies' retirement.

"It was so dangerous for me and Casey and Bautista. A📖lso, when the smoke was gone, I had all the oil in my visor, so I didn't know if I had oil on the tyres as well."

Stoner, who lost a place to Stefan Bradl as he ran wide through the smoke, added: "I found myself in the𒊎 middle of the smoke, unsure where I was going and what I might hit and we lost positions again."

Dovizioso went on to🌳 finish third and Stoner f🅘ourth.
