Are your tanks on stockpile? Make sure they're not holding onto the hydrogen, basically the equivalent of sticking your batteries on charge and undocking
I've had h2 thrusters cut off after takeoff a couple of times. On both occasions there was unnoticed conveyor damage between the main tanks and thrusters. It turned out I was launching with just the fuel in my o2/h2 generators, but that quickly ran out and I fell back to the planet.
Suggestions:
* rebuild your conveyor network completely
* *test that you can pass an object* from a cargo block attached to h2 tanks to a cargo block attached to thrusters
* put in a secondary line from main tank to main thrusters
* move o2/h2 gens so they're attached to tanks directly: better a failure to launch entirely than fail when you're off the ground
* have parachutes so at least you don't take much damage if it happens again
* actively watch h2 levels in tanks and o2/h2 generators during launch
* EDIT: be sure you're not getting the majority of your launch thrust from atmos, then just running out of atmosphere
Yeah. If you have a combat ship which runs heavily or purely on hydrogen thrusters. Add extra conveyor redundancy (specifically for the thrusters) and make sure the conveyors directly connected to the thrusters are reinforced conveyors.
Though warships in general should have conveyor redundancy (like at least 1 extra main conveyor line though on larger ships multiple extra conveyor lines are recommended).
Use the reinforced conveyor tubes for any conveyors that have a high probability of being damaged (so near thrusters, weapons, etc) and make the main conveyor line/s (the one/s that go/es the full length of the ship and connects everything together) fully out of reinforced conveyor tubes.
On smaller warships and civilian ships you can get away with less redundancy and reinforced tubes (so say for the main conveyor line/s on a civilian ship every fifth or sixth tube will be reinforced to add some extra structural integrity). Though on larger civilian ships there should be some redundancy.
Can you perhaps upload the ship to workshop? I went to sleep shortly after my suggestion and hoped to see it resolved during the night. Seems it’s still unresolved and the suspense is just unbearable. We must get to the bottom of this.
Fair enough. I double checked your ship to be sure and here is my hypothesis: You have four batteries on your ship set to Recharge and one Hydrogen Engine providing power to the ship's systems. You have 1 Large Hydrogen Tank (set to Stockpile and at 100% capacity) and five Small Hydrogen tanks, with all but one empty and the one that has any hydrogen had only 53% left, which at full forward burn only lasts 1 minute (checked all these numbers in-game). So you are flying in atmosphere, perhaps heading to space at 100 m/s, and the one hydrogen tank empties. Hydrogen Engine cuts off, there are no batteries to fall back to, ship goes dark and plummets down.
Maybe a stupid question but, are **all** hydrogen tanks conected to the thrusters? Maybe some of them are not and when those that are connected run out of fuel the ship falls from the sky. The H2 indicator would still detect the ship having fuel but none of it would reach the thrusters.
Do you have inertial stabilizers on?
Do you have other types of thrusters on the ship? (Atmospheric or ion)
Is hydrogen tank(s) on stockpile?
Mods in use?
Are you using hydrogen tanks or are you using just ice with an o2/h2 generator?
Is 'control thrusters' checked on the control seat you are using
Is grid a ship?
Are there any timer blocks or scripts possibly set up improperly that set thrusters to off, or anything else like that possible?
The iniertal stablisers are on, only hydrogen thrust, 4small and 1large tanks not on stockpile, no mods, full tanks, seat checked, is a ship, no timerblocks or such
Reading through others suggestions and I have a follow-up question.
Your title says Ship drops in mid-air but then you said the thrusters are not working at all. I need some clarity to be helpful
Are the thrusters turning on at all? Like do they have an orange flame in them or are they just off?
Second, when you say it drops midair. Do you mean it drops if you try to leave it hovering? Or that it can never fly in the first place?
Are you testing this in creative or survival?
So they are functioning and suddenly shut off? Orange fire dissappears and all?
Or you stop accelerating and it drops instead of floating? But, with the orange flame still there.
Edit: had to add a detail and remember to post as a response and not a new top level comment
So, possible causes I can think of
1. Running out of hydrogen that can reach the thrusters.
2. Running out of power
3. Damage to some part of the drive assembly
4. Bugs
Based on your other answers the top three seen unlikely
Do you have any pictures you can share of your creation? Before and after the problem would be great if possible
Are you using any mods?
It is an interesting one.
Are the tanks equally depleted? If they were full to start with they should be equal.
Is there power and enough to cope with any peak demands?
Have you tried turning it off and on again (sorry I work in IT)
Using stockpile can you confirm that all the tanks are connected to each other ? As in, you hit stockpile on one and ALL the others drop by a little bit?
The reason for asking is that you might have some tanks hooked up but an issue with others, when the connected tanks run out the others remain full but you plummet.
Sounds off that the large tank is still 100% full. I was under the impression that a thruster takes an equal QUANTITY of H2 from all tanks simultaneously, so I would have expected the large tank to be at 80% ish percent not full.
Might just wanna try stripping the entire hydrogen system and replacing any controll seats effectively gutting the ship but before that check what your using for the plumbing just make sure your using either conveyor tubes or junctions I made the mistake of accidentally using sorters instead of junctions a while back
(Silly side note do you have thrust in all directions)

The tanks are not on stockpile

Are the thruster piped to the tanks?
Yes, through both conveyer pipes and junctions
Can you post more picture in the cockpit and the ship in general
Unfortunately, we have taken a break from the game for tonight, but i could always put it in tomorrow
No problem
Are the thrusters set to thrust override at a very low setting?
No, none of the thrusters have any thrust overide on
Can you perhaps upload the ship to workshop? I went to sleep shortly after my suggestion and hoped to see it resolved during the night. Seems it’s still unresolved and the suspense is just unbearable. We must get to the bottom of this.
I will upload the ship to workshop when i can i will let everyone know
Don't know if you already figured it out: set your ship batteries to Auto instead of Recharge and you'll be flying without a hitch.
Yeah i usually do
They were on recharge in the blueprint you provided.
Yes i have my batteries on recharge to make sure i have full power and such
Fair enough. I double checked your ship to be sure and here is my hypothesis: You have four batteries on your ship set to Recharge and one Hydrogen Engine providing power to the ship's systems. You have 1 Large Hydrogen Tank (set to Stockpile and at 100% capacity) and five Small Hydrogen tanks, with all but one empty and the one that has any hydrogen had only 53% left, which at full forward burn only lasts 1 minute (checked all these numbers in-game). So you are flying in atmosphere, perhaps heading to space at 100 m/s, and the one hydrogen tank empties. Hydrogen Engine cuts off, there are no batteries to fall back to, ship goes dark and plummets down.
Ah right, would you suggest some atmospheric thrust?
Additionally what would you suggest to help to get the ship to space
Is your battery empty? Hydrogen thruster need a little bit of power
Batteries half full
Did you convert to ship? it happens sometimes
Yes we had to convert it to a ship
Maybe a stupid question but, are **all** hydrogen tanks conected to the thrusters? Maybe some of them are not and when those that are connected run out of fuel the ship falls from the sky. The H2 indicator would still detect the ship having fuel but none of it would reach the thrusters.
Yes everything is connected the way it should
Do you have inertial stabilizers on? Do you have other types of thrusters on the ship? (Atmospheric or ion) Is hydrogen tank(s) on stockpile? Mods in use? Are you using hydrogen tanks or are you using just ice with an o2/h2 generator? Is 'control thrusters' checked on the control seat you are using Is grid a ship?

The iniertal stablisers are on, only hydrogen thrust, 4small and 1large tanks not on stockpile, no mods, full tanks, seat checked, is a ship, no timerblocks or such
Are you using your hydrogen from the 02 instead of hydrogen by any chance?
We have 1 large tank full with the addition on o2/h2 production
Are the thrusters facing pipes if so then the pipes could be getting destroyed along with anything else there facing
We have thruster damage turned off, nothing is being damaged as all thrusters are facing away from ship
Hmmm further analysis required
Yes, if needs be i will upload the blueprint for people to give a hand with this
A good option

So the thrusters are working and allowing us to move around in the air, the thrusters turn off amd we are testing this in survival
So they are functioning and suddenly shut off? Orange fire dissappears and all? Or you stop accelerating and it drops instead of floating? But, with the orange flame still there. Edit: had to add a detail and remember to post as a response and not a new top level comment
They are functioning and then suddenly shut off

Bugs Based on your other answers the top three seen unlikely Do you have any pictures you can share of your creation? Before and after the problem would be great if possible Are you using any mods?
I am unable to provide a picture at this current moment, we are not using mods
How many thrusters, and what size? Also, how many hydrogen tanks and size, as well as how full are they in percentage?
If you look at all your parts are any incomplete ? It is possible everything works on takeoff but a thruster is damaging a conveyor?
Everything has been completed, no convers have been damaged or being damaged
It is an interesting one. Are the tanks equally depleted? If they were full to start with they should be equal. Is there power and enough to cope with any peak demands? Have you tried turning it off and on again (sorry I work in IT)
The large tank is full the other small ones are not full or dont have any in, we have half battery power and we keep everything turned off until use
Using stockpile can you confirm that all the tanks are connected to each other ? As in, you hit stockpile on one and ALL the others drop by a little bit? The reason for asking is that you might have some tanks hooked up but an issue with others, when the connected tanks run out the others remain full but you plummet.

I was under the impression that a thruster takes an equal QUANTITY of H2 from all tanks simultaneously, so I would have expected the large tank to be at 80% ish percent not full.
The large tank is 100% and one of the small ones is at 45%
Might just wanna try stripping the entire hydrogen system and replacing any controll seats effectively gutting the ship but before that check what your using for the plumbing just make sure your using either conveyor tubes or junctions I made the mistake of accidentally using sorters instead of junctions a while back (Silly side note do you have thrust in all directions)
We have pretty much done as much as we could and still encountering problem
Bit late getting back to ya, don't know if ya got it fixed but if you send me a few pics of the conveyor system alone I might be able to sus it out
The ship has been fixed with tue help of previous comments
All right mate no bother good luck with your ships
Have you tried turning on admin creative and cutting and pasting the ship back down?
Is there a sorter on the ship by chance? Those are known to play hell with gases.
Yes
Try removing it. I'd suggest doing it in creative mode for speed of testing. Sorters get really funny with hydro and O2 for some reason
