2 Red Fireballs travelling North to South

2 red craft about 15-30 seconds apart seen travelling North to South, slightly Southwest. Night was clear, other planes and their lights clearly visible. Altitude I would best describe as about double the height of a standard helicopter flight altitude. Much too high for any helicopter and I am sure I would make out the lights if it were a conventional aircraft as it was much lower than the other 3-4 planes visible in the sky in different regions. The other planes lights were very clearly distinguished. There was definitely no blinking pattern, but rather a pulsing - very similar to how fire behaves - no pattern and no pauses like a conventional aircraft, just different intensities. In both cases the shape could not be determined other than oval and the lighting had a glow circumference I would estimate to be about the same as the crafts radius. Flight path was steady and straight. Both craft had the exact same heading. Both craft were identical. Speed w! as nothing out of the ordinary that I could distinguish from other traffic. I was able to really study the lights as they did not speed away too quickly. Both slowly dimmed then vanished completely as they approached my nine o'clock direction (I was originally facing due north, 12 o'clock where I saw them approach from my 11 o'clock). The size was a bit hard to judge. At first glance I swore it was a helicopter but it was just too high. I have never seen a helicopter fly that high, especially so close to 2 different airports (one commercial, the other for private flying). But the size could come close to that of a helicopter if it were that high. No distinct sounds heard - too much background noise to hear any plane.

I am used to aircraft sightings as we are near 2 airports. We see all varieties of aircraft both civilian, commercial, and military.
