Yes, I see them on the wing "Go Fetch" missions or delivery missions, but you can still accept the wing missions without a wing, just takes longer to complete with only one ship depending on your cargo capacity. But they are still good to take to get the G5 data or materials, just wish I could find some with consistent cracked ind firmware stuff, all I see are the exquisite focus crystals and mod embedded firmware, with a few other worthless data types or material types that can be found almost anywhere. I need missions that I can't find just anywhere, and cracked is one of them. I've tried the old tried and true data point scanning on the surface Med Sec planetary installations, but its no longer true, after several tries, never once did I get the cracked stuff. Although, can get them at Dav's Hope, but when it does give off the cracked, will only give you 1, and it may be 3 or 10 relogs before it gives you another one. So for me, the only way to get cracked anymore is to trade for em, which is still a long process because the data that I have plenty of and can get frequently, ain't worth much on the trade, so have to piecemeal enough cracked for the upgrades I am wanting, since it is used for both the G5 PD and Thrusters, and some other things as well.
But a note on the wing delivery missions, I found one last night that sent me to take x amount of stuff to a station one jump away, 10 mil, for 3 runs back and forth solo, so take it, get to the station to deliver, check the mission board, and wouldn't you know it, another wing delivery mission taking stuff back to the station I just left, nifty, now can make a profit both ways, and keep checking the board for more stuff to bring back and forth. Sure helps increase your rep in multiple systems that way. Just avoid the BH missions for now, the C&P killed that profession, cause heaven forbid, you incur a bounty for 'reckless' damage, and then you get locked outta the system yer in, if its your home system where all your ships are parked, good luck.....and don't get scanned by the station....
