Totally agree. You could see the wheels spinning in DM's head as he sat there playing the "victim"; totally stunned, resigned to the fact his dad had made an exit because of the financial pressures.
Fact is, it had only been a few weeks that they had their license, and IIRC, AS had a heated discussion with DM about getting his toys and junk out of the hangar so they could get potential clients in and contracts signed. IMHO, WM never thought for a minute that he'd be opening the doors with a full slate of clients. With a state of the art facility, I'm of the belief that WM would have attracted more than a few. DM simply figured he could have the hangar for his own use if WM and the MRO disappeared.
Considering WM had a sound understanding of what he was doing, it's impossible to believe that he didn't think it was going to take at least a year to get money flowing. To think that a business this size, with this much capital invested was going to turn a profit in 3 weeks is absurd. Being stressed over the performance/attitude of his son is more plausible. AS wanted the place ready to go- DM had no place to take his hobbies. The guys really running the MRO would have no use for SS chiselling off VIN numbers over in the corner. Unfortunate for WM, DM had to kill the MRO.
