Help ID some aircraft I saw at Oshkosh

First there was a Navy carrier based fighter, designed to get up to
altitude in just minutes to take on the kamakazies. A gentleman in
his 80's described this high performance bird in glowing terms. What
is the name of this bird.

Next I am trying to find out the name of a new 6 place kit aircraft
which is turboprop powered. Had it on my old system but the system
died and could not save the web addresses. The name and web address
would be good.

thanks
