Corrected entry: This happens until the end of the series. When the Delta Megaship is found, it attaches to the Astro Megaship, and they travel around together. However, throughout the series, the Delta Megaship is constantly disappearing and reappearing.
Corrected entry: When Adam shows Alpha the old Mastodon morpher, Alpha claims that the Power Coin was destroyed ages ago - this is not true. Only the Zords were destroyed, not the Coins.
Correction: Actually in "Ninja Quest part 1" when Alpha tried to provide the Zords with more power he ended up causing a power surge which caused the power coins to short circut (Hence the damage shown on Adam's morpher), which is why the rangers never used the Dino Coins after that.
True Blue to the Rescue - S1-E18
Corrected entry: The Turbo powers were destroyed in "Chase Into Space" part 2, at the end of series 5 - Justin shouldn't of been able to morph into the Blue Turbo Ranger.
Correction: The Blue Turbo Powers could possibly be powered by Storm Blaster for this mission (it was Storm Blaster who gave Justin the Turbo Moprher and key).
That's a nice theory. But it's still a mistake. Then again it's tough to explain all the other power rangers returning with their powers.
Correction: They do not "attach and travel around together". They only ever combine during Megazord battles to form the Astro Delta Megazord. They never attach in ship mode.
They're referring to the Delta Docking Station. The space station type platform that the Delta Megaship was kept in and the Astro Megaship would sit on top, from time to time. But yes they do not ride together all the time and it's not appearing and disappearing.
