Yesterday (May 6, approximately 12:15 local time) I watched a Westjet 737 climbing out of Thunder Bay from runway 07. I was a bit concerned at the climb out for 2 main reasons:
1/ The climb was extremely shallow, closer to the sink rate when on approach.
2/ That 737 was smoking something bad from the starboard engine, yet it didn't appear to be turning around to return with some type of engine trouble.
I can't think of any reason for the shallow climb out, as there was no other air traffic in the area I could see to be avoided.
Any thoughts on this?
