Looking at the 4C in terms of cash, rough quarterly revenue is equivalent to projected quarterly cash outflow leaving $2.5 mil buffer so we're not likely to see a CR this quarter which is good. Threats of CR always see price drift lower.

SP appreciation triggers flagged in 4C;

 -  B737-NG OEM Approval

   -  Formal approval from the FAAfor a new STC allowing CVM application to  WiFiradome structure on aircraft (3 months time-frame estimated and Q3/Q4 fleet installation start target)

   - Installation of 3 x 757 CVM kits for evaluation & training

   - Making of decision (or not) to install 757 CVM Kit to Delta Fleet (H2 2019)

I was under the impression the 757 decision was a foregone conclusion and installation was due at next major fleet maintenance grounding so for me the timeline I had in mind seems to have slipped again and there still is risk present in this application. 

There are 4 clear events (above) with the potential to trigger significant shareprice appreciation an of course, new developments can pop up at any time.
