Thats correct. Wish I had seen them together, the sight and sound would of been amazing.

Perhaps when the one in Lincolnshire is back in the air we might get to see all three together.
Restoration started in the late 70s and finished late 80s.
A few of the planes from the museum fly over my home occasionally. The Lancaster sound is so distinct, can’t imagine what the really big 1,000 plane raids sounded like.
That’s abit Thunderbirds.
Logical end-game of RATO I guess, something that proliferated in the era of underpowered aircraft of all kinds, even seaplanes -
Still used to (e.g.) get aircraft up and away quickly in “hot” sites like Helmand, but perhaps the best (worst) rocket-assisted-everything has to be Operation Credible Sport - luckily for all involved they never actually tried it…
I’ve mentioned the Harwell ‘incident’ before, I think.
In the 1960’s a USAF military jet put down on the (by then) disused and rather too short RAF Harwell runway, having mistaken it for the intended runway at RAF Abingdon. He managed to stop the plane but they were now faced with the problem of getting it back to where it should have been. In true gung-ho can-do fashion they decided to try RATO. Mistake. One of the rockets failed as the plane was rattling down the runway. The other one pushed it off the runway and straight for the AEA site fence (think working experimental reactors, unprotected stores of radioactive materials). Fortunately it was brought to a stop before it hit anything messy. Sense prevailed. They took the wings off and loaded it onto a truck, as they should have done in the first place. Then they grassed most of the runway over. Then they planted trees down the sides of it.
I’ve got a gliding ‘experience’ coming up next month which is going to involve a couple of winch launches. I did ask if we’ll be able to fly around a bit over Dartmoor and was resoundingly told ‘NO’. I asked why & they said ‘There’s nowhere to land’ And there was me thinking you got up, glided about for a bit wherever you liked, and then gracefully descended. I’ve realised that gliding doesn’t exactly have a future as a means of transport!
It’s brilliant though. You’ll have a great time
Quite a few bloody great big ones towed behind powered aircraft left Harwell as part of the D-Day operation.
Some could carry jeeps or even light tanks
The Pegasus Bridge Museum and Memorial was a real eye opener. The size of the gliders and the payload was extraordinary…
Happy to tie some rope to the roof rack to get you up. 
Dont be daft, he doesn’t want to go supersonic.
If I had to pick a favourite plane - absurd as that notion is - this would be the first that came-to-mind 
I’m lucky enough to get to visit Lt Cdr Chris Gӧtke At his parents farm from time to time some amazing stories and an immensely talented pilot.
