I had updated the game, i have updated the aircraft mod. I do not have train tunnels activated.
I can make cargo plane, but the other three are not available . cant see them in research tree.
What else can I do.
No conflicts shown with Mod

Based on what you say, the most likely thing is that you enabled the "non-combat" mod setting. Currently that setting is slightly broken, so if you have it enabled you'll have to start a new save once you disable it.

As a workaround, (if you don't mind disabling achievements) you can run the following commands to complete the researches once you've disabled the non-combat mod setting.
/c game.player.force.technologies['gunships'].researched=true
/c game.player.force.technologies['jets'].researched=true
/c game.player.force.technologies['flying-fortress'].researched=true
/c game.player.force.technologies['napalm'].researched=true
