Apparently there were three bases from Kent to Yorkshire in Englandicon devoted specifically to aiding crippled aircraft returning from combat. Here's what I found:

"Each had three unusually long and wide landing strips enabling damaged aircraft to recover safely when their chances of reaching a conventional runway were marginal at best. The single 9,000 ft strips were built at RAF Manston in Kent, RAF Woodbridge in Suffolk and RAF Carnaby in Yorkshire. At 750 ft wide, they were more than five times the width of conventional wartime runways. Divided into three lanes, the northern and central lanes dealt with aircraft returning under flying control, while the southern lane was reserved for more serious emergencies" (read: crash landings).

It's more than likely that Dick Abbott landed at one of these three fields.
