Wish I could cargobob the skylift for that sell mission.
On the return trip with the second Skylift I genuinely considered landing on the train and letting it ferry me back. Longer route but twice the speed.
The Skylift has a huge rotor disk, so even if it stayed on the train without exploding, everything near the tracks would hit it.
I just reviewed my video of that sell mission and I'm glad Rockstar programmed it like they did: my second container hit the barge on target (and counted as delivered) but bounced over the barge wall and ended up in the water
