Aeroplane Heaven B17 Bomb Bay Doors

Hello all

I am having some difficulties in opening the bomb bay doors for this great aeroplane

In the manual it says to press SHIFT/E+4, but that opens the cockpit door, not the bomb bay doors

In my control assignments there is no combination like that

Can someone tell me the description of the assignment please?

Thanks!

So first press SHIFT+E, release, then press 4

Figured it out

Bye!
