The Switchblade was never released.
AA26 "Switchblade", as it was named, was a tactical variable geometry aircraft. It was capable of reaching Mach 1.5.
Unfortunately my phone was accidentally formatted, and I lost progress on it. RIP.
But don't worry, I plan on building a Version 2.0 of EVERY SINGLE ALIENINDUSTRIES AIRCRAFT (AA14, 22-28) which will have higher detail and parts. So no loss on that.
