Hello, I have been following this mod for some time now. I love how you have put a ton of attention into EMS and Fire in terms of strategy and realism. Vertical ventilation has been a long time want in EM4 mods for me as well as interior attack. HIHFTY just doesn't feel right .
One thing I'd love to see in terms of realism is a random ETA for the helicopter. This would make transports and EMS calls a lot more stressful and realistic.
Here's one flight service that is stationed near us. I think they have some of the best liveries I've seen on a helicopter.
