Issue with Assault

After finishing 4 of the assault quests in Boralus for the ‘‘A Sound Defense’’ quest, you are asked to take a gryphon to attack the horde gunship. Once you’ve filled up the progress bar you get a message saying ‘’, the gryphon is all ready to go!’’. So naturally I’m taking the heavily highlighted gryphon when I get back up to the top of the deck. Upon arriving back in Boralus, you apparently also need to kill a captain that I missed. Already arrived back in Boralus and no gryphon to take me back to the gunship.
Does this mean I simply have to pass completely on this Assault, just because of this?

You can try asking POLITELY someone to help with by carrying you back to the gunship in their twoseater flyer (or in their backs if druid).

I assume you don’t have BFA pathfinder on your account, otherwise you can just fly there yourself.

(lvl 60 learns flying and CAN indeed fly around in BFA, no that you want to…)
