Irish Paralympic stars Jason Smyth and Michael McKillop have both clinched gold medals at the IPC World Athletics Championships in Doha.
Smyth, 28, won the fifth world title of his career by retaining his T13 100m title as he clocked 10.62 seconds.
The sprinter is travelling home on Saturday night for the birth of his first child, who is due on Sunday.
Smyth's room-mate McKillop retained the T38 800m title 90 minutes later in a season's best time of 2:01.31.
McKillop, who is from Glengormley on the outskirts of Belfast, will be favourite to win a sixth IPC world gold medal when he defends his T37 1500m title next Friday.
Three-time Paralympic gold medallist McKillop, who has a mild form of cerebral palsy, moved into a big lead after 400m and while Tunisia's Abbes Saidi cut into the advantage, the Irishman held on to win by 1.03 seconds.
"I knew what I had to do. It was a planned performance," said McKillop following a victory which came after another injury-affected season.
"There was no winging it today, especially when you aren't 100%, you need to know what you are doing.
"They were catching me down the home straight. I was hanging on for grim death.
"My legs were starting to give way and usually that doesn't happen to me but it shows if you aren't 100% fit, these things can happen."
McKillop's latest victory maintains an unbeaten record in Paralympic competition which stretches back to his 1500m silver medal at the 2006 IPC World Championships in Assen.
Smyth to dash home for birth of first child
In the earlier T13 100m final, visually-impaired Smyth finished a comprehensive .28 of a second ahead of Brazil's Gustavo Henrique Araujo.
Smyth is a four-time Paralympic champion having achieved T13 100m and 200m doubles at both the Beijing and the London Games.
"I'm glad to have taken care of business," said Smyth before he made his dash home from Doha to be with his pregnant wife Elise.
"It's great to have the first part of it done. The baby is still holding in there and I think I'm going to be home in time."
Australian Chad Perris (10.96) took bronze final behind Smyth and Araujo with Britain's Zachary Shaw sixth in 11.33 seconds.
