Perhaps they should try dropping some cheap dummy fairings out of a Hercules to test their retrieval technique smile
The fairing is 5.2m wide.

A Hercules cargo bay is 3m wide.

I think you see the problem.

That (design/build/develop/maintain a bespoke 747 for the purpose) would be the NASA solution.

The SpaceX solution is just to incrementally test recovery of the fairings with each successive launch, as they are happening anyway.

Additional development costs and delays: practically zero.

Ok then, a folding spring loaded fairing that expands once it exists the aircraft! wink

What about a C-17?

Or a C-5?

Both are military, hence unrentable.

Edited to add: an AN-124 is big enough to do this, and is commercially available.
Also edited to add: reading up on the AN-124, it turn out that this is actually how SpaceX are moving the fairings from Hawthorne to the Cape anyway!

The USAF has dropped all sorts of civiliian space related stuff out the back of its aircraft over the decades.

There are only two 747s in the world capable of carrying large objects on their backs - and they are both retired. In any case, they only ever air launched Shuttles for a very brief period in 1977 - and it was an extremely dangerous series of tests that were carefully planned for over a year in advance.

I think the An 124 is the only realistic option - although where such a test could be carried out is open to question.

There’s another Falcon 9 due to launch on Sunday. I don’t think they need to chuck any more fairings out of aircraft to test them.

Aye the fairings are expended anyhow nothing really lost trying to recover them and they need to do it from much higher than a 747 can go

Not sure to be happy or sad I don’t recognise that guy.

The next launch from Vandenberg is in a month’s time, so hopefully they’ll have a bigger parasail by then.

He looks like the bugler from "F-Troop" (Corporal Dobbs?).

It's Gilligan, from Gilligan's Island; mind you that fairing's 5 meters across, so he's grown a bit.

I’ve heard of it, but It was cancelled before I was born & I don’t remember ever seeing repeats. Apparently they showed 13 episodes on ITV in London in 1965, but Granada in the north west showed reruns for years after that. I used to live in the Yorkshire TV region as a kid.

My grandmother lived in Manchester and I always felt sorry for people who had to watch Granada, due the odious Stuart Hall on local TV. Turned out my instincts were right about him.

I enjoyed his work on "It's A Knockout" - but then, I was only 13 at the time.

I wonder if they've considered building an underground silo to build rockets in... could then be raised up for launching so the build area doesn't get destroyed if the rocket blows up on the pad smile
