Some unsolicited constructive criticism.  (Forgive me!)  One rule of thumb that filmmakers live (and die) by is that you don't want to keep to a single shot for too long.  There are some exceptions, but if you try to keep your shots under say, 8-10 seconds a piece, you won't lose your audience. 

The problem I had is that take-off is such an exciting time.  The power, the speed, the noise, the sheer volume of things going on simultaneously.  You keep that shot too long, and it feels slow.  You don't capture the "romance" of a take-off.

Keep 'em coming!
