"around the hundreds of km long bomber stream", surely not for US daylight bombing in close combat formation, maybe for BC night bombing.

Juha is correct. Use your imagination to picture 20 boxes of 50 B-17 and B-24's per Box for a 1000 bomber mission. Recognize that each Bomb Division (1st B-17, 2nd B-24, 3rd B-17) penetrating German airspace in one long column.
At some point, say Brunswick, one long foramtion of 1st BD (~350 a/c in seven boxes) continues to Berlin. The Second Box heads SE toward Mulhausen then breaks for Leipzig. The 3rd Division heads SE then East for Halberstadt. The mission is co-ordinated to plan a route point for the formations to re-join at Kassel and return home en masse,
If this mission occurred in mid April 1944 - ALL of the Penetration Escort P-47 FG's (approx 5 including 9th AF) that were escorting the three BD (2 each ..P-47 FG to cover seven boxes of bombers strung out over 20-30 miles).. so one FG covering 175 bombers in 3-4 boxes each. Max effort = 48 in three squadrons of 16 - one above center 'essing, one out in front and one in trail.
There are five Mustang Groups (4, 354, 352, 355, 357) and three Lightning Groups (20, 55 and 364) now hitting the R/V with responsibility to split up and cover the 1000 bombers going to three (or more) locations. So, the division of labor is about the same as the P-47's.. two cover one BD of 350, two cover another BD of 300, two more cover the third BD of 350 and the last (Mustang) group sweeps out in front of the Berlin strike force.
Density of US Fighters per cubic mile is very low. Far lower than the LW 'eyewitness' can claim.
If you 'do the math', the LW can easily place 200 fighters on one or two boxes and expect to run into zero or at most two Fighter Groups IF the LW makes first contract and MAINTAINS contact. In that example, specifically Munich on April 24, the LW put 225 fighters between Ulm, Augsburg, Erding, Munich, Oberphaffenhofen and Landsberg - covered by the 355th and 357th only. 98 Mustangs against 225 is not a very bad ration for the LW. This example is NOT unique.
Simply put, the LW experten that claimed 'swarms' of Mustangs engaging them was hyperbole and exaggeration for the most part.
