Narrative:

I was #4 in flight of 4 military aircraft deploying from home station btl to dma, with stop-overs at szl and cvs. As I climbed on my own IFR flight plan out of the WX (tops approximately 14000 ft), I caught sight of my element leader and informed him on FM radio. Distance between our aircraft is estimated to be 5 mi or so. Element leader informed ZAU that I had visual contact, and declared 'marsa.' after about 1 min, as I momentarily looked away to do a time/fuel usage update, element leader received clearance, INS direct to szl. After I looked up, I could no longer see leader. I continued to look for him for approximately 8 mins as I climbed to FL220, with no IFF on and no IFR clearance (canceled by marsa). I turned towards szl later than lead, then turned south of heading in a futile search for element lead. I finally informed lead, who initiated radio calls to ZAU, which assigned me a discrete IFF and rapidly effected an IFR join-up. I've been around long enough to realize this (my actions) were very stupid, very unprofessional, displayed very poor judgement in not contacting element lead immediately upon loss of visual contact.

Title: FLT OF 4 MIL A10 ACFT ON CLB WITH MARSA IN EFFECT. RPTR LOSES SIGHT OF LEAD BUT CONTINUES CLB TO FL220 WITH NO ATC CONTACT.

Narrative: I WAS #4 IN FLT OF 4 MIL ACFT DEPLOYING FROM HOME STATION BTL TO DMA, WITH STOP-OVERS AT SZL AND CVS. AS I CLBED ON MY OWN IFR FLT PLAN OUT OF THE WX (TOPS APPROX 14000 FT), I CAUGHT SIGHT OF MY ELEMENT LEADER AND INFORMED HIM ON FM RADIO. DISTANCE BTWN OUR ACFT IS ESTIMATED TO BE 5 MI OR SO. ELEMENT LEADER INFORMED ZAU THAT I HAD VISUAL CONTACT, AND DECLARED 'MARSA.' AFTER ABOUT 1 MIN, AS I MOMENTARILY LOOKED AWAY TO DO A TIME/FUEL USAGE UPDATE, ELEMENT LEADER RECEIVED CLRNC, INS DIRECT TO SZL. AFTER I LOOKED UP, I COULD NO LONGER SEE LEADER. I CONTINUED TO LOOK FOR HIM FOR APPROX 8 MINS AS I CLBED TO FL220, WITH NO IFF ON AND NO IFR CLRNC (CANCELED BY MARSA). I TURNED TOWARDS SZL LATER THAN LEAD, THEN TURNED S OF HDG IN A FUTILE SEARCH FOR ELEMENT LEAD. I FINALLY INFORMED LEAD, WHO INITIATED RADIO CALLS TO ZAU, WHICH ASSIGNED ME A DISCRETE IFF AND RAPIDLY EFFECTED AN IFR JOIN-UP. I'VE BEEN AROUND LONG ENOUGH TO REALIZE THIS (MY ACTIONS) WERE VERY STUPID, VERY UNPROFESSIONAL, DISPLAYED VERY POOR JUDGEMENT IN NOT CONTACTING ELEMENT LEAD IMMEDIATELY UPON LOSS OF VISUAL CONTACT.
